I think this is the correct thing to do as far as copyright law goes, but it seems to me that copyright terms are far too long to fulfill their original purpose: incentivize the distribution of creative works. Originally copyright was for relatively short terms (20 years IIRC). It is now life of the author + 70 years or 95 years from publication if the copyright holder is a corporation. Some organizations advocate for perpetual copyright terms as well.

Given the extremely long terms now available there is little incentive to quickly extract value from the copyrighted work. Patents exist for the same reason and have been similarly coopted by their holders.

Edit: if copyright terms were shorter publishers would be incentivized to keep their games in print and to update them for newer media/platforms.

There are so many ways that copyright duration could be adjusted to dramatically reduce the duration for out-of-print not-for-sale works while simultaneously allowing Disney to keep Mickey Mouse.

The fact that it's a single fixed duration that continues to be extended for just a minuscule fraction of works is ultimately the issue.

Honestly, I'd like to see something more along the lines of the copyright lasts the lifetime of the author unless it gets sold.

Once it gets sold it immediately starts a shot clock of exactly 20 years.

Though honestly anything would be better than what we have now.
