GOG as an example would have been better. But you didn’t choose that. You chose a system that DOES have DRM and DOES act like a publisher and takes a cut. That isn’t a good way to sell your “new system” when Steam does EVERYTHING the “old system” does.
Given that you can see a different comparable example, and yet instead of just going "yeah like GOG", or thinking to yourself "yeah GOG would be a better example, I get what he means though", you're going "YOU didn't SAY gog WHAT an ASSHOLE", I again, urge you to reflect on whether you're having a good faith conversation or whether you just have a stick up your ass about something and are venting online.
And no, Steam prevents people who haven't purchased a game from playing it. You are fundamentally not understanding what I'm writing if you're not seeing how that's different from a system where everyone has access to everything.
Go back and reread my comments, you have evidently not understood anything I wrote.
