This petition is worded in such a way that it almost feels like lying.
Most games that shut down aren’t doing so because they had an arbitrary ping home that breaks them, it’s because hosting servers is fundamentally part of the game’s multiplayer-oriented experience.
You’re trying to use the former to backdoor in a way to force the latter to give you all of its server code.
Assuming this law were to go forward with even the most rigorous knowledge of the problem-space, and an intentional push to require multiplayer or server-based games to give you their server code after the game is shut down, all that will do is increase the risk involved in creating any multiplayer games.
Most likely this will reduce the quality and variety of games that get created going forward, which would ironically make preservation much easier.
