In early January, the artist and technologist Daniel Howe opened an email from Google informing him that his three-year-old ad-blocking app, AdNauseam, had just been banned from the company’s Chrome Web store. Overnight, he discovered, the free app’s 60,000 users had lost access to the app on Google’s popular browser, and all comments, ratings, reviews, and statistics had vanished.

Ads are the economic powerhouse of the internet, supporting much of its “free” content and services, this website included. But they are also easy to hate, making the internet distracting, ugly, slow, and more costly to use. This partly helps explain the demand for ad blockers: Installations grew by 30% last year to 615 million computer or mobile devices, or 11% of the world’s online population, according to estimates by Page Fair, an industry group.

Google and its parent company, Alphabet, which dominates the market for online ads and made an estimated $79 billion from them in 2016, has taken a largely hands-off approach to the potentially existential threat of ad blockers. And, according to recent reports, it now plans to include “ad-filtering” software pre-installed in Chrome—an “if you can’t beat ’em, join ’em” approach to making the web less annoying.

But AdNauseum isn’t like the other ad blockers: It takes a more activist approach. Rather than just concealing them, the app sends noise into the system by automatically clicking on ads in the background, muddling efforts by advertisers and ad networks like Google’s to determine your preferences and your identity as you browse the web. Alan Toner, a policy consultant at the Electronic Frontier Foundation who studies ad blocking, calls AdNauseum affectionately, “a piece of agitprop theater” designed to “creatively protest the surveillance mechanism behind advertising.”

“NO CLARITY AT ALL”

Google, however, didn’t complain about AdNauseum’s approach to protesting ads. Instead, it pointed to a developer agreement that gives the company “the right to suspend or bar any Product from the Web Store at its sole discretion,” and offered a more prosaic reason for the ban:

Baffled, Howe wrote back to ask Google how this rule applied to AdNauseum. In a second email, a company representative explained that an extension should not perform both blocking and hiding ads. In an email, a Google spokesperson confirmed to me that the company’s single-purpose policy was the reason for the app’s removal, not because it automatically clicked on ads, but wouldn’t comment further.

To Howe and his cofounders, designer and activist Mushon Zer-Aviv and NYU information science professor Helen Nissenbaum, this explanation is hard to accept at face value. Many ad blockers, including uBlock, Adblock Plus, Adblock, and Adguard, both hide and block ads, trackers, and malware, and yet all of these are allowed in the Chrome Web store; AdNauseum had been in the store for two years.

Instead, the team suspected a simpler motive behind Google’s decision: AdNauseum directly conflicts with the way that the company makes most of its money.

“Why would [Google] allow almost any other ad blocker to also block malware and only block us for doing so?” said Zer-Aviv.

Alok Bhardwaj, the founder of the Epic browser, which has had its own privacy-related clash with Google, said Google’s explanation reflected “strained logic.” But he also said that AdNauseum’s click-all-the-ads approach raised the threat of ad blockers by an order of magnitude.

“If there’s considerable doubt over whether an ad click is legitimate or not, that’s a big problem for Google charging for ad clicks,” he wrote in an email. “It could undermine Google’s business model more severely than plain ad blockers, so it’s probably their thought to ‘nip it in the bud.'”

“The official reasons offered for their exclusion have been so generic as to provide no clarity at all,” Toner said. “Its exclusion needs an explanation.”

ADS AREN’T JUST UGLY: THEY’RE INVASIVE

Google’s decision to ban AdNauseum was only the latest salvo in an ongoing war over online advertising. The industry and publishers have recently been fighting back against ad blockers, for instance, by requiring visitors to disable them if they want to view a page. In August, Facebook announced it was blocking anti-ad software across its platform. And while AdNauseum is the first desktop ad blocker Google has blocked, it has previously banned mobile apps like anti-tracking tool Disconnect and ad blocker AdBlock Fast from its Android Play Store, citing a rule that says one app can’t interfere with another.

The ad industry also knows that ads can be a nuisance, and it’s taking pre-emptive measures to make them more palatable—or, in Google’s case, to block the unpalatable ones. “We feel like there are a lot of challenges in advertising. There are a lot of wrong ways,” Darin Fisher, vice president of Chrome engineering, told CNet last year. But “if publishers and advertisers do ads the right way, it can be great for the users and for the ecosystem.”

But Google’s positions also point to a crucial disagreement at the heart of the ad war: What makes ads such a nuisance to begin with?

Advocates insist that ads aren’t just ugly, annoying, and bandwidth-sucking: They pose a risk to privacy, as the networks of software behind ads—cookies, trackers, and malware—watch not only where you go on the web but, through your phone and your purchases, what you do in real life. This data, which helps data brokers better understand you, includes everything from your health to your shopping and financial habits to your political and religious views.

But privacy is largely missing from Google’s discussion of problematic ads, says Howe. By avoiding mentioning AdNauseum’s actual intent, Google’s explanation for banning it echoes the advertising industry’s discussion of web ads, which focuses on aesthetics rather than privacy.

“Google does not want the ad-blocking debate to be about surveillance and civil liberties because it has very weak arguments to make there,” he wrote in a post on the blog of Princeton’s Center for Information Technology Policy. Instead, “it would like to keep the debate to the economics and aesthetics of ads…”

With a built-in ad filter for Chrome, which commands an estimated 60% of the browser market, Google could continue to frame the debate in terms of aesthetics rather than in terms of privacy.

Google’s ad filter would be based on standards drawn up last month by The Coalition For Better Ads, a global coalition of advertisers cofounded by Google and including industry groups, publishers like Facebook and The Washington Post, and advertisers like Proctor & Gamble and Unilever. (Apple, which permits third-party blockers on its Safari browser, and Mozilla, which includes anti-ad features in its Firefox browser, are not part of the Coalition.) The new guidelines urge the rest of the industry to stop using the kind of annoying ad formats that have fueled the rapid rise of ad blockers, like pop-ups, auto-play video ads, and full-screen ads. But the standards do not mention tracking or user privacy.

“By banning AdNauseam and then rolling out its own ad blocker, Google is now trying to prevent anyone else from drawing the line in the sand when it comes to which ads are presented to the user,” Zer-Aviv said. Google would be “leveraging its near monopoly in the ad and browser markets to forcefully exclude any competition that does not align with its model of ‘acceptable ads,’ be it other ad networks, the Do Not Track standard, or privacy initiatives like our own.”

Google’s advertising business depends upon tracking more than ever. A little-noticed change to the company’s privacy policy last year gave it the ability to track users’ web activity across a majority of sites and apps. (In a concession to privacy, the company also now allows users to change their default settings to “opt-out of ad personalization.”)

Google’s ad blocker could give the company more leverage over advertisers and other ad blockers that have recently launched so-called “Acceptable Ads” programs, which permit some ads to be shown that are deemed to be “non-intrusive.” Google and other major ad networks already pay to participate in AdBlock Plus’s acceptable ads program, which provides the bulk of revenues for Eyeo GmbH, the company that makes the app.

A Google ad filter could also effectively suppress a new Do Not Track standard. The older standard is essentially an automated request from your browser, asking the websites you visit to refrain from tracking you. The new version of DNT, developed by the Electronic Frontier Foundation, is dynamic: It asks websites not to track you and it knows if they comply.

In its most recent update, AdNauseum permitted sites that complied with the Do Not Track policy to display ads to users, and refrained from clicking on those ads. (Because Google does not comply with DNT, the app blocked Google resources such as Doubleclick.net and Google Analytics.)

Howe thinks the new DNT feature may have contributed to Google’s decision to boot AdNauseum from the web store.

The standard may be threatening to Google, Howe wrote in his blog post, “perhaps because it could represent a real means for users, advertisers, and content providers to move away from surveillance-based advertising.” If enough sites adopt Do Not Track, “there will be significant financial incentive for advertisers to place ads on those sites, and these too will be bound by DNT, as the mechanism also applies to a site’s third-party partners. And this could possibly set off a chain reaction of adoption that would leave Google, which has committed to surveillance as its core business model, out in the cold.”

Toner, of the EFF, said “it does seem like a strange coincidence” that AdNauseum was banned soon after it integrated support for the new DNT standard. Privacy Badger, the EFF’s own Chrome app that blocks cross-site trackers, also supports the new DNT standard, but it has not encountered problems with Google, he said.

Cable companies are also seeking a piece of the marketing pie on which Google, Facebook, and other digital media giants are already feasting. The bill President Trump signed last month to repeal privacy rules for internet service providers will allow those companies to collect and sell customers’ browsing data to third parties without their express consent.

The playing field is growing ever more sophisticated too, as companies combine web data mining with personality behaviors gleaned via Facebook to better profile consumers and target them with ever more persuasive ads, be it for pop stars or politicians. “We think that ISPs should not be helping track their users,” said Cooper Quintin, a security researcher and programmer at EFF.

Nor do most Americans, according to a survey by YouGov and the Huffington Post. Seventy-one percent of the public—and 72% of Republicans—believe the FCC’s privacy rules should have gone into effect (see the interactive chart below). Some states, meanwhile, including Minnesota and Washington, are contemplating new privacy rules to pick up the slack.

Users who want privacy from ad tracking can use a variety of free and subscription-based software to defend themselves. Toner suggests installing tracker blockers like Privacy Badger, Disconnect and uBlock, beefing up ad-blocker software with the Easyprivacy filter, and turning off Acceptable Ads in AdBlock Plus or AdBlock for Chrome. Browsers like Firefox, Epic, or Brave also include ad blocking and anti-tracking features.

Meanwhile, new technologies for ad blocking, including a prototype “perceptual” ad blocker developed by researchers at Princeton and Stanford, promise even more effective ad blocking in the future. And despite Google’s ban, AdNauseum still works in Firefox and Opera, while enterprising Chrome users can manually install the app in developer mode.

NEW PRIVACY LAWS

Legal changes are also on the horizon. A new set of rules in the European Union called the General Data Protection Regulation, scheduled to go into effect in May, will require all companies serving the region’s more than 500 million residents to receive explicit consent from those users for ad targeting or risk paying prohibitive fines—as much as 4% of their global revenues.

The impact of the EU rules on ad targeting could be global, and could dovetail with efforts by some advertisers to improve the way they distribute ads. Currently, the complex ecosystem of online ads is rife with click fraud and distribution schemes that make it hard for advertisers to know if ads are actually being viewed and what kind of content their ads are appearing next to. Building more transparency and simplicity into the system could benefit not only readers but advertisers and publishers too.

Even after the new EU laws, privacy proponents are likely to continue trying to build better blockers, and companies like Google will keep trying to make that work difficult—or build their own.

Google will likely maintain the upper hand. To Zer-Aviv, the company’s banning of AdNauseum was less about compliance with rules (the policy that Chrome apps should not have “multiple functionality”) than about a show of force. He interpreted Google’s “multiple functionality” argument as trying to “force us to compromise our software’s security”—by requiring the app to remove its malware-blocking features—”so we can be easily discredited.”

But in recent weeks, the team decided to change course: It amended AdNauseum so that it would not block malware, in order to meet what they thought was compliance with Google’s policy.

Again, the app was rejected. In another email, Google cited the app’s “multiple functionality” as a problem, Zer-Aviv said. “I think this pretty much seals the question about Google’s sincerity on the reasons for the ban against AdNauseam.”

As he and his cofounders argue, real progress in online privacy isn’t about the option to see less annoying ads: It would require corporate policy and government regulations to align to give users an option to fully opt out of online tracking if they want to. Until that happens, anything less isn’t much of an option at all.
