it's not just politics either. perrin already sorta pointed out a separate issue which is how twitter's algorithm forces political stuff onto your feed, Elon has made this even more of an issue since he boosts his own tweets to everyone, which are 99% politcal. but on top of that twitter has for a long time just been about negativity, even when Dorsey was in charge I would find that I would be fed drama or rage bait posts, and that's because anger is a very strong emotion that keeps you using the app to see people get dunked on and whatnot.
