I honestly think he’s intentionally driving Twitter into the ground. Thing is he can’t just fire everyone and shut down the servers or he won’t get the tax write-off. He’s burying Twitter in a way that maintains tax status. So in a way that’s smart, but also stupid he spent what he did only out of spite.
What he’s doing to Twitter is like a jumbo jet pilot that commits suicide by crashing the plane (that’s actually happened). Why do you need to take all those innocent people with you. Just go jump off a building, same end without killing a bunch of innocents.
Really his destruction of the platform is about control, he has some kind of personal beef with Twitter so he used his power and money to kill the whole thing. He’s taking his bat and ball and going home.
