Unfortunately that will happen irrespective of the law.
If you want permissive rules then corporations will just resell your IP (like we see with SaaS). And if you want tighter rules then you just create a higher barrier for entry that benefits corporations rather than independent entities.
Either way, it’s easier to operate when you already have a leading position.
Then just outlaw big corps. Put a hard cap on company size or capital, possibly on a per-domain basis. Or just put what has to be big infrastructure under direct state control. Worked wonders in practice in France.
Oh, and also put a hard cap on individual wealth while we're at it. No one, no matter how hard working, deserves a billion dollars. And no one should be trusted with that much power, it's too goddamn dangerous.
(The caps should be indexed to stuff like median income or wealth. Wanna get richer? There's a way: help everyone get richer. That way we're actually in this together.)
