I mean, big media companies (e.g. Disney or Nintendo) specifically seem to believe that copyright should give them the right to basically rewrite their own history however they please - e.g. by "un-publishing" old movies or shows when they would conflict with a planned re-release of the same franchise.

That's a desire that IMO directly conflicts with society's desire to keep history. So as long as we have powerful groups that specifically want the ability to erase parts of history, historians will have a bad time.
