Yeah there have been efforts since game servers without server software for consumers to run themselves were first commercialized, to prevent this outcome where profit motivation and shortsightedness will lock us out of so much. It's good this effort seems to be getting somewhere in the current system.
I can't stop thinking how remarkable it is that Doom spawned the speed running phenomenon, and people use specific version builds of those early entries, yet some of its most recent entries like DOOM (2016) are without playable version archives because of extremely preservation-hostile DRM schemes. Fuckers need to publish at a minimum all previous builds DRM-free for customers once a version is cracked, before DRM implementation in entertainment software can be banned entirely.
Oh, and I want source code + assets on file with a library of Congress or equivalent in different places for publication once it becomes abandonware.
