In my opinion (removed from the whole AI controversy) is that intellectual property law has been long abused, not by artists and creators but by publishers and studio owners who have used their landlord-esque positions to take control of most art, and then extend their IP rights while denying the public a robust public domain.

The idea that a strong public domain is beneficial to all culture has been lost. Now we have huge court cases because two different songs use a similar progression of notes. The point of copyright should be to motivate people to create more art, not prevent people from doing it.

Take the whole Under Pressure/Vanilla Ice fiasco. Nobody listening to "Ice Ice Baby" is going to then say to themselves "great, now I never have to listen to Queen again". They are both very different songs in different genres, that use the same guitar riff.

I understand why selling pirate DVD's should be illegal, for recently made movies that are still under print, but transforming a work should not be infringement.
