It's more about maintaining infrastructure than ownership. If you buy a game on Steam and Valve can later delete it from your library it's about ownership. If a company shuts down the central server and the product stops working it's more about planned obsolescence. The same issue affects many IoT devices, not just video games, and I think protecting those is more important as it affect more consumers and generates e-waste.

But I know stop killing games just gets a lot of coverage on lemmy because there are a lot of gamers here. I'm sure people also write petitions and talk in EP about more important topics like climate change and human rights.
