Reminds me of when the RIAA and MPAA were able to end piracy. Dark days.
So you can still pirate, but most people don't. Maybe LLMs will be the same, sure you could use an uncensored/unlicensed model that doesn't pay royalties to publishers, but why risk it?
I think, in general, there are relatively few completely ideological 'pirates.' People will buy things when they can easily afford it, and it's easy to do so. When it's too expensive, not locally available, or when the payment methods involve hassles, they will simply download it instead.
This might not last with the fragmentation of streaming services (I don't think people are ready to pay $10x10 for access to all services).
Open source models generally do not have that option. Maybe there are some exceptions like Meta using some private data in future Llamas, but I question how sustainable those efforts are.
Most streaming, AFAIK, is not P2P. Streaming gives you instant access to the content, and streaming clients are often simpler to use, with features such as recommender systems, etc.
