@dangillmor Fascinating. So, 16+ years ago I ran a website called Liberated Games. My goal was to collect the games which writers/publishers had given explicit permission could be free, and thereby ask others to consider doing the same. Sometimes it was just source code, sometimes it was assets too.

Here's an old Reddit post which backs me up: https://www.reddit.com/r/gaming/comments/6af0v/liberated_games_free_legal_games_for_download/

Anyway, to see the term I coined back then, "Liberated Games", is kind of neat.
