Facebook and Instagram, via Mark Zuckerberg, and X/Twitter via Elon Musk, are already in Trump's camp and are helping him.
This law gives Trump leverage over TikTok - their access to the US market will likely depend on serving Trump's interests. Like X and Meta (and other SV companies) operating in other countries, they will comply with local oppression. It's incredible that the Democrats keep handing victory after victory to their opponents.
(Trump also is gaining extreme influence over professional news media, including Fox News and the WSJ, of course, but also ABC News, possibly CBS News, the Washington Post, CNN, MSNBC, the LA Times, and many more. It may be time to stop the lazy criticism of the NY Times and start taking them seriously; they could be the only island left in the storm, and will be subject to extreme attacks.)
