Yeah, the unfortunate thing is reigning in one monopolist today seems like more an invitation to the other monopolists.

How many potentially world dominating mega-corps are there? Google, Apple, Microsoft, Facebook, Amazon, Musk-corps, OpenAI, Nvidia...

It seems like any reasonable rejigging of things would require attacks on multiple sources of monopoly. And any other attack on a given player is just going to strengthening other players.
