ChrisGamer300: I'm not sure why Stadia of all things would provide DRM free stuff though since it's the most draconian drm there is, always online and streamed from Googles own servers.
It doesn't hurt to propose and express your demand for it. Otherwise DRM proponents will have easy time saying "you see, no one needs it, and no one asked".
shmerl: You can read the proposal, it answers your question ;)
SirPrimalform: I read a bit of it, it just didn't really seem compatible with my current understanding of streaming gaming services.
That's the whole point. You, like many, assume streaming = renting. That doesn't have to be that way, which is explained In that thread with examples.
Linko64: 'Buy a game (let's say Linux build with Vulkan support and all, but compatible with desktop Linux) and download DRM-free version.'
I mean this is the stark opposite to the whole angle they're going for. It's also based off far too many assumptions and broad requests.
Google employees themselves said, to send them proposals. So, why not. Instead of saying it's impossible, show some support for the idea with your comments and upvotes, or propose even better ideas yourself ;)
