But life of the creator + 70 years?

Without copyright, it would be perfectly legitimate and legal for someone to not follow a license (because it would bear no legal weight because of the lack of copyright).
I would argue that open source is best served by strong copyright protections that allow the people created the software to make sure that further changes to it are released back to the community. Weakening copyright law means that it is that much easier for big companies to co-opt some software and not need to release the changes back.
People probably would have less of a problem if microsoft breached the license on 100 year old code.
As long as Microsoft can and will wield those laws against me? Darn tootin'
This is also why I fully expect Steamboat Willie to fall out of copyright protection in January 2024 - right on schedule. There's a few countries that have supra-EU copyright terms, but none of them are dealmakers. Nobody is demanding we match Mexico's life+100 terms, for example.
