Fwiw I can see where you’re coming from, but I don’t really understand why/what for. Game Pass isn’t really comparable to Steam or a digital storefront anyway, which already makes the comparison kind of silly. That said, I recognize you were going off the other commenter’s framing in the argument there, so not faulting you for following along with it. I did just the same in my reply before giving it some more thought with this one.
Nevertheless, it is worse in terms of ownership, but that was never its selling point to begin with, so it’s silly to criticize it in that respect, much as it would be to criticize Netflix for not providing ownership of what it gives access to. Also regarding Steam DRM, xcjs covers that nicely in the other reply here.
