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 think a lot of people are ok with their platforms and work around the censorship without moving. The number of times I've seen "unalive", "secs", "oui'd" on tiktok. The most realistic outlook is that people will keep filming the crimes on these platforms and tagging them "geezer" and "isn't real".
