Having a reputation for being a neutral haven for electoral fraud and calls to violence isn't exactly a great thing to aspire to. (Falsely claiming an election is illegitimate, refusing to recognize its results, threatening election officials into awarding you a victory, and stopping its certification is, in fact, a form of electoral fraud.)

It's unfortunate that a major political movement in the US has aligned itself in support of those two things, but having done so, it forced Twitter's hand.
