you now have a significant percentage of the educated populace thinks he's an asshole at best and fascist at worst; this was most not the case before he bought twitter and went full-MAGA

I'd call that a fail.

Also, he was supposed to "save" Twitter and make it into a bigger social network and "everything app" (like WeChat). He instead decimated its revenue and so poisoned the brand that it'll never become an "everything app" other than among the same people buying $Trump coins.
