X is already a far right echo chamber, if you create a new account and navigate to the "for you" page, all you see is Elon Musk, Alex Jones, Andrew Tate and other far right "role models".
It's unfortunate that X still retains a greater reach than its alternatives, but that can change in the medium term.
I follow a bunch of Japanese game developers, who at present don't have a strong motivator to leave X. Most of them are also on LINE, but I'm a little reluctant to try it since I don't actually read Japanese. (ETA: I looked at LINE just now and it seems more like a chat app than a board where users post information for anyone, so I think it's off the table.)
Then just don't navigate to For You. I wish I could just see my friends on Facebook (those are the people I care about), but I can't turn off crappy suggestions.
With X I can control my own feed by using the followers tab.
The For You page is just an example, Musk appears everywhere on the platform, watch a video, swipe it and a video of Musk (totally unrelated) pops up. X is basically a right-wing propaganda machine now, which is one of the reasons I don't use it.
