It took a while for the DMCA to happen after Napster. But it indeed happened, and we all know the saying about history repeating itself.
By the time they came for Napster technology had already moved on. I can still download entire albums and movies in minutes 2 decades later. Heck, Usenet is still a bastion of piracy and that's been around for 46 years.
Yeah, but you cannot do so legally; you can't build a business of it. The AI companies are trying to build a business, not download movies for their kids to watch during school holidays!
The 90s young people are familiar with are... way different from the 90s I remember. Their understanding of it is like... if someone asked to AI-gen the decade.
I suppose my point still stands if you are willing to stretch back to Usenet, BBSs, etc. as an inflection point in mass copyright infringement.
