I mean I kinda agree with you, but for 15 bucks a month is it really such a big deal? If the service went away tomorrow I wouldn't really care at all... I enjoy it, and it enables me to game on a level that would normally require thousands of euros of equipment, so .... Yeah, I don't care about gaming freedom it seems.. I still want OSS for my OS though ;)

You do own them in GeForce Now, not sure in Stadia/Luna. You're renting the gaming PC, but you can install those Steam games on whatever machine you choose. Though perhaps Steam is the GAAS.
