Meta lets Instagram and Facebook users in Britain and the European Union object to the use of their information for its AI, and Americans get no such option, 404 Media reported on Wednesday.

The form matters because of a change to Meta’s Commercial Terms for business accounts that takes effect on Nov. 20. The new language lets the company “use any content from such domains, web pages, or URLs to provide, develop, improve, research, train, and maintain the integrity of” its products. That covers websites that are simply linked to a Meta account. Artists and small-business owners who depend on Instagram and Facebook have been angry about it, Samantha Cole of 404 Media wrote.

Nieman Lab broke the story on Oct. 15. Three legal experts told the outlet the terms could be used to argue that Meta may scrape news sites and train its AI products on what it collects. A day later Meta took the word “train” out of the list of permitted uses and narrowed them to “advertising and business products,” where the earlier text had covered every Meta product. That edit still leaves Meta plenty of room to use the material in building products.

“This is not about scraping news sites, and these updates don’t give us new rights that supersede those preferences,” Daniel Roberts, a Meta spokesman, told The Verge. He meant publishers’ robots.txt files, which tell crawlers what they may take. The revised terms don’t promise to honor those files, Nieman Lab reported.

The terms were first due to take effect on Oct. 30. After the backlash, Meta moved the date for both the Commercial Terms and its Self-Serve Ad Terms to Nov. 20. A Meta spokesperson told Nieman Lab the delay would give the company time “to explain to our partners and stakeholders what’s changing and what’s not — including how Meta uses web crawlers and the fact that content owners will still be able to use robots.txt to signal preferences.” As of Oct. 23, the date was the only thing Meta had changed, according to Search Engine Journal, which cited Nieman Lab.

Users in Britain and the EU have been posting the steps. An Instagram user, bookish.sil, showed how to do it on mobile: open the menu, go to the privacy center and tap “object,” which brings up a form that asks why. Meta later sent an email saying the objection had been approved. Another user, jenniqueart, posted a walkthrough and got the same result.

Ms. Cole’s accounts are based in the United States. With a VPN set to a London address, she found a page in Instagram’s privacy center where she could object to the use of her information for Meta AI, and a separate option covering third parties. Neither appears when she’s in the United States.

The form still didn’t work for her. Clicking through returned an error: “This form is only available to people in certain regions.” A VPN connection in Belgium got the same message. She wrote that the form might depend on where an account was created rather than where its user is, and said she had asked Meta to clarify.

The objection rests on European law. The General Data Protection Regulation, enforceable since 2018, includes a right to object to the use of one’s personal data, and Britain has its own version. There is a limit for business accounts, though. The rules “only apply to personal data about individuals; they do not govern data about companies or any other legal entities,” the European Commission says, though information about a company can count as personal data if it identifies a person.

The pressure isn’t only coming from users. Senator Adam Schiff, Democrat of California, wrote to Mark Zuckerberg asking him to drop the terms, and gave Meta until Monday, Nov. 2, to explain how it would address users’ concerns. The Movement for an Open Web, an advocacy group whose members include advertisers and publishers, has asked the European Commission and Britain’s Competition and Markets Authority to block the terms while they investigate. Meta’s changes also include a no-opt-out clause for business websites, which rews reported this month.

Meta keeps changing its platform, so the steps may not work for everyone, Ms. Cole wrote. For users outside Britain and the EU there’s no form at all. “Unless something changes before November 20, the rest of us are screwed,” she wrote.
