Those laws have re-shaped the entire internet.

I don't know who said "destroy" but COPPA and the DMCA have had a lot of negative effects. And some positive ones too, but it's hard to argue they succeed in their objectives at all really, and easy to see the harms.

They didn't destroy the internet, but they did embolden the platforms at the cost of smaller players, who couldn't step up

Questionable.

The DMCA is pretty terrible.

GDPR is fine. The only annoying thing about it is the petulant malicious compliance banners that some sites started using in response. Unfortunately it didn’t destroy the ad/tracking based internet, but that was probably too optimistic.

The GDPR has had huge and shitty impact on the entire internet. It's night and day with cookie banners on every website. DMCA has pros and cons. But it's clear the lack of real penalties for bogus copyright notifications leads to abuse.
