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 you can verify you're shadowbanned. Open your comment in a private tab and see if it's there.
