Well, for Twitter it's fine. It's a private company, and the shareholders can only blame themselves for the management they put in charge.

(From a broader society point of view, I'm a bit sad that they didn't actually manage to run Twitter into the ground. I think Twitter's a net-negative for humanity. But that's a different topic. People obviously like using it.)

I don't think hanlon's razor applies to billionaires , unless the peter principle holds true all the way to the very top
