I don't thing the premise of the question is right, he is not tanking Twitter, he is transforming a stagnated company that he overpaid for into something else that may or may not tank.

Remember some things he discussed in his messages, like Twitter becoming a protocol and essentially acting as infrastructure like a phone company that doesn't care what you are talking about as long as you pay your bills?

Yeah, that's not happening because he spent tens of billions of his personal wealth, got other investors whose motives might not be as pure, loaded the company with debt that has yearly interest payments larger than the profits of the company in good times and the "pay $8" thing didn't work well.

He simply can't keep Twitter in the form he purchased Twitter, so he is shaking it down to try make something out of it. He will try all kinds of things until something works or Twitter shuts down. Not doing this and keeping Twitter the way he purchased it means Twitter shuts down eventually anyway and without anything to show for the money he spent.
