I feel like the TikTok ban is only the start.
The US is pissed that it couldn't 100% control the narrative on Israel genociding Palestine and sees the internet as the reason why. They've already put a lot of effort into homogenising and controlling the narrative on most big social media sites. I wouldn't be surprised if they started cracking down more under the guise of "stopping misinformation"
I mean, more than what's already been happening? I feel like as time goes on, and they gain new insights, awareness and technical ability to censure, they will jump on those opportunities immediately. In other words, we're not just getting by right now on the platforms we enjoy out of their willingness to play fair, or their benevolence; once they have the chance, they'll go for it
