Games made before I was born whose copyright won't expire until long after I'm dead. They ought to be public domain by now. In fact, games should have a shorter copyright term since they're harder to preserve and less valuable over time. I still have a box legally-purchased of Zork games (CDROM editions) and manuals and a copy of Planetfall here, but should I feel any shame about pirating them? I don't think I should…
All copyright is way too long but authors go completely off-piste at anyone who suggests that it should be something more reasonable (I kinda like 21 years myself). Part of the issue is that the loudest voices are that 0.01% of authors whose work still has some commercial value decades after its creation.
I sell code (programming libraries, and commercial business systems) which have been under continual development sint 1996. So 27 years.
Copyright in this context would be complicated in a "20 year" model. Last month saw a significant upgrade to a product first released in 2000. Should the 2K version be public domain now?
I get the main complaint, especially in the context of old games like infocom (which are abandoned). It feels like those should move gracefully to public domain. But on the other hand there are those of us who do still make a living from old, but active, code.
I do agree that current copyright is absurdly long, but I also understand why Disney et al see ongoing value in their creations and are prepared to lobby for that value.
I don't think there's a simple fix here, one which covers such a wide set of circumstances. All the fixes I've seen proposed are "great for x, terrible for y".
