You definitely don’t get it. One, this is a future date to take effect. Two, these companies already have a way to run things locally - without Internet services. That’s how the development works. This would force companies to release that local version when they decide to no longer support the game. So like how a lot of multiplayer games already work - steam has a server version that you download, run on a computer, and connect. Nobody who built these games wants them to be unavailable at some future point
