The headline is misleading. One of the five FCC commissioners said this, not “the FCC” as suggested by the headline, and in the same interview that commissioner said “as an FCC official, his own capacity to regulate TikTok is limited; CFIUS, the Commerce Department or the Federal Trade Commission may have greater legal authority over the company” and “he has not met with CFIUS member agencies or the White House to specifically raise the issue”.

It’s a guy thinking out loud. He’s an important guy, but on it’s own this changes nothing.
