Twitter rules are not law, so by law they can do whatever they damn well please. Including banning your account randomly, deleting any tweet they like, or anything in between. Legally, they owe you or any of their users exactly nothing. However, you also owe them nothing - you can stop using Twitter any second. Which I wholeheartedly recommend to everybody. I did it years ago and it's not hard. If you don't like what they're doing - just walk away.

Of course, that doesn't mean we still can't criticize Twitter - but walking away should be the first step.
