While you may be correct I think you’re still missing the point. CLI is for super nerds. While you and I may know how to use it, the average person doesn’t, and is unlikely to put in the effort to learn. That is the innovation that Apple made in bringing computing to the mainstream. It was precisely because people didn’t have to learn how to navigate the CLI environment and instead got an easy point-and-click interface that computers caught on with the public at large, and that gained Apple an absolute ton of cash money and noteriety.
I must not, because I see zero difference between Steam and GoG in this regard other than the fact that Steam provides a bunch of side services that GoG does not. Otherwise they’re both just selling you a revokable license to play a game.
