As always, copyright is a supressor of creativity, not an enabler. Copyright terms should be 10-20 years max, or up to death of an author.
Even current regime is ridiculous.

0-5 years commercial copyright - the author/creator has total say on any and all commercial use, fair use doctrine applies. Years 6-10, extended fair use: mandatory attribution and 15% royalty but otherwise unlimited for public use in any context, for any reason. Years 11+, goes to public domain.

Simple system. Encourages creativity, 99% of all money made on media (books, music, movies,etc) gets made during the first 5 years after publishing.

No grandfathered works, no lineages of families who had a creative relative back in the 40s getting to coast through life by bilking the rest of the world on their fluke of genetics.

Current copyright is a sick joke designed to enrich lawyers and wealthy IP hoarders, and screw the public out of money on a continual basis. We don't have to live like this.

Until it changes, pirate everything.

The system of copyright enshrined at the time of the founders is drastically more restrictive than this, which undercuts your "sick joke designed to enrich lawyers" line.
