For a half billion dollars or so Elon could buy substack. It's a private company in the midst of a very painful and difficult fundraising cycle, they may not have much of a choice but to sell. Twitter would get a functioning monetization engine which favours creators, and apparently a functional product team.

Heck, he could keep the substack exec team under a heavy earn-out as the new Twitter exec team and declare victory, and go back to playing with rocketry and sports cars. Just returning his attention to Tesla would probably increase his net net worth with the acquisition.

Instead he's taking the pettiest of all paths. I genuinely feel sorry for him at this point, it's got to feel awful right now. I don't understand why one of the world's richest people would willingly subject themselves to his Twitter experience. He can afford to let go his ego this one time, he has nothing to gain and nothing to prove.
