The text limit inherently causes reductivism and “hot takes” which lack nuance and spread misinformation.

I'm confused. Are you trying to imply that long articles do not do the same thing? Everything on the internet is clickbait and outrage fuel these days. Not just on Twitter. It's prevalent on reddit, which I would say has been the epicentre of much more serious problems than twitter ever caused: theredpill manosphere community which has evolved into Andrew Tate today, incels, pizzagate, etc.

I think if we compared the damage done by every platform out there Twitter would actually be at the lower end. It's great at causing a lot of extremely minor drama and arguably creates a lot more minor shit than other ones (which probably drives its high activity), but has generally avoided causing extremely serious shit unlike other longform platforms.
