The Trump administration's Federal Trade Commission has removed four years' worth of business guidance blogs as of Tuesday morning, including important consumer protection information related to artificial intelligence and the agency's landmark privacy lawsuits under former chair Lina Khan against companies like Amazon and Microsoft. More than 300 blogs were removed. On the FTC's website, the page hosting all of the agency's business-related blogs and guidance no longer includes any information published during former president Joe Biden's administration. These blogs contained advice from the FTC on how big tech companies could avoid violating consumer protection laws. Removing blogs raises serious compliance concerns under the Federal Records Act and the Open Government Data Act, one former FTC official tells WIRED. During the Biden administration, FTC leadership would place "warning" labels above previous administrations' public decisions it no longer agreed with, the source said, fearing that removal would violate the law. Since President Donald Trump designated Andrew Ferguson to replace Khan as FTC chair in January, the Republican regulator has vowed to leverage his authority to go after big tech companies. Unlike Khan, however, Ferguson's criticisms center around the Republican party's long-standing allegations that social media platforms, like Facebook and Instagram, censor conservative speech online.
