If you’re talking about being forced to code as in “make the game work on it’s own without the server”, I’m thinking a “working state” includes “here’s what you need to run the server privately”, no more coding should be necessary.
Idk if you were thinking they’d be legally compelled to convert server based multiplayer games into peer-to-peer, but that’s not how I see it.
It should also not be legally possible to prosecute restoration work to make unsupported games run on private servers.
