Regulation needs to be seen as a trade-off, for example: We get better behaving companies, and the cost is less risk taken. Then the question becomes "is the benefit worth the cost?"
All regulation by default is anticompetitive and also comes with the risk of intended consequences, and thus must prove that they provide sufficient benefit. They are "guilty until proven innocent".
e.g., rather than trying to "just do something" about games, maybe we should revisit copyright law as a whole, instead of slapping a bandaid on a festering wound caused by the first bandaid
This could be as easy as releasing the tools they used for development when developing the game.
Most game studios are similar, in reusing and improving a whole development architecture and systems across many titles. I would not agree with making them release that, even an older version. That's a big competitive moat for some studios.
I think if a community group wants to PAY to operate a server, that's quite reasonable. And then you still end up with a fight about how much to charge. But I don't think handing over server code is the right move.
