Some people also manage to extract millions of profit from Youtube and Instagram channels, despite all of the content being free. Books are not that different from any other medium.
Honestly, I'd much prefer that model for books over the forced Adobe DRM or vendor-specific stores that the industry seems to be trending towards.

Expecting direct payment for any knowledge product experience is a poor idea to carry on to extremes like plays & skits. If today someone finds a lost manuscript by a great ancestor author then they own the copyrights to it the moment they publish it. But we wouldn't have the Iliad without mass copying. In a way our imprisoned OP is a perfect reciter of plays who is doing his bit to ensure the plays that do get made remain true to human spirit not deepening state tentacles.
