Yeah some niche communities that have nothing to do with extremists or politics at all are only on Twitter/X unfortunately.

You're giving them money and engagement with which to continue. Having your eyes on that content and then returning the next day to see more is explicit approval of that content. And having those ads served to you makes Elon money which he then uses to serve more ads to everyone.
