i'm fairly sure the point (whether calculated, or more likely, mostly not) of having politics moved there is because there is no political topic that could be discussed properly there. it makes for good, distracting noise.
it makes for a lack of meaningful critique, or for that critique to be instantly buried in bad actors. noise is a shield. noise is easily dismissable.
monetized social media, in general, is made to be clickbait, to feed negative emotions because that's what gets people addicted to outrage, it steers people towards thinking less and reacting more. nuanced discussion and thoughtful spaces are drowned out and cast aside for the loudest and most obnoxious players. this is appealing for someone trying to uphold the status quo or push society towards hate.
i don't think it's a coincidence that politicians have moved there, that spaces have become so polarized and negatively charged, and that the most prime example of both of these happenings is xwitter. everything is connected in this big, terrible, and vaguely randomly evolved system. i do think evolution is the best word for it. what lives, survives to propagate. it doesn't matter how healthy it is. the result is this blind, meandering, gargantuan worm, following the scent of blood, feeding on the worst of it all.
xwitter is easy and, notably, if you're a powerful white man, you can build your base with no accountability. it exists in this space where it's the most serious news source that almost no one takes that seriously. of course it's appealing.
