I don't know, for the past few years Elon has seemed more passionete about trolling on Twitter than literally anything else in the world. One of the first changes after the purchase was to make it so that his tweets got special rules so they show up to everyone whether they like it or not. He currently posts on it a gazillion times per day.

Maybe in the future his attention will drift elsewhere, in which case yeah he'll let the company die without a second thought, but we don't seem to be anywhere near that point these days.
