I’m not a lawyer, but one way I think this could play out:
Until it gets stayed, which I’m guessing will be coming pretty soon, could people who felt they were libeled by Trump’s tweets sue Twitter? Enough of those lawsuits may tip Trump’s presence on Twitter from being to Twitter’s benefit (bringing eyes to the platform) to their detriment (force Twitter’s legal team to respond to these suits.)
As soon as that happens, it would be to Twitter’s benefit to ban him. If the board resists, that could open them up to a lawsuit from shareholders claiming that their actions are not maximizing the value of the company as they are obligated to do.
