Yes. A limit on how long before announced server shutdown a game is allowed to be sold (with it otherwise having to allow refunds) would already go a long way, and that is something I’m in full support of. I’m not signing that petition though because it seems disconnected from reality.
“Just make games playable in offline” works for some games (and if planned from the start wouldn’t be that hard to implement), but ranges from “define playable” to “utterly insane” for others (imagine WoW servers shut down, is it in any way sensible to require allowing offlinr access?).
A more extreme but imo still reasonable variant would be forcing the open sourcing of server code and everything required to make networking work, with the license allowing self hosting of game servers. But even this can still be obstructed, because “open source” doesn’t have to mean “publically accessible code repository”
Well, it’s the gut bacteria of those insects doing the breaking down, so it is still microbes. Just microbes hosted by worms.
