It wouldn't entail either of those, or at least doesn't have to. Idk about this specific law, but the SKG movement has made it clear that companies saying "here you go, you figure it out" and posting their unmodified backend source code/programs and leaving it to end users to figure out how to run it is acceptable. The big problem without it is that a lot of stuff in modern games is just straight up encrypted and impossible to decrypt, so once the central server is gone you're completely screwed.
