All companies should be required to release their entire codebase under the GPL if the product is no longer going to be maintained by them.

I play several games that run on 20+ year old engines, long since abandoned by their original creators. The community reverse engineered the games and server infrastructure so they can still be run and enjoyed today. Same for all the folks who develop emulators and the entire ecosystem of ROM dumpers, readers, and handhelds that surround them.
Capitalism is a cancer. So amazing that, at least in certain parts of the software world, we have something better.
