I think it depends on which kind of entrepreneur you're aiming to be. VC breakups are amazing if your goal is to box in and become a market competitor. But as of the last decade or so there's been plenty of "incubators" to take into account. startups whose goal is instead to be sold off to some major company and get their payday that way. Those kinds of models would deteriorate, and are likely what want to prop Big Tech up.

I do hope we have more genuine competitors fighting out there for breakupps. But it's hard to say these days.
