CDRomance is a ROM site whose main specialty is offering pre-patched romhacks, fan translations, undubs, etc. and it's a great resource for such things for systems up to the PSP. I think they were deliberately trying to stick to retro systems to stay under the radar but predictably that didn't prevent the copyright ghouls from coming for them eventually.
Businesses that are not equitably owned and operated coops should not be allowed to hold copyrights at all, nor should they be allowed to receive exclusive licenses or otherwise sneak around it by controlling a property without directly owning it. Copyright should further be tiered: a tier that never expires, which requires non-coop businesses to acquire proper licenses to use it; a 50+ year tier that requires coops to seek licensing; and some shorter tier that would require an individual artist or author to seek licensing for commercial use. Anything owned by a coop that dissolves or an artist who dies without transferring ownership should immediately enter the public domain, except the requirement for businesses to seek licensing should remain and be negotiated by, idk, some relevant industrial union or something and the proceeds to that should go towards grants funding independent creators or a healthcare fund or something.
Under a socialist system this should be further reformed, as needed for the context of however media is produced under the new system, to balance the need to protect a given artist's ownership over their creations with the need to prevent them from holding something hostage that's become the work of a great many other people involved in its production - so a novelist may own their own works and be able to refuse to see them adapted, but one writer out of several for a series can't claim piecemeal ownership over it and try to sabotage its ongoing production over a falling out, for example.
