I guess you could say I don’t disagree but at the same time Musk is so wealthy that it’s hard to say it’s foolish.
If X shut down entirely Musk’s life wouldn’t change in a material way. Twitter was legitimately “cheap” enough for him that it was an impulse purchase. And of course, it’s not like the wealthy pay cash for such things.
He wanted to own Twitter and remake it in his own image. He got exactly what he wanted.
