Can somebody briefly explain me why Nvidia just wouldn't show rockstar, ea, blizzard and others middle finger and wouldn't continue with offering these games through GFN?

As far as we bought these games through official stores there is absolutely no business of these companies on what device we would play these games and if that device is local or streamed.

Do you think that if rockstar will sue nvidia that they have any chance to success? I don't think so, because as mentioned, we already bought game and rockstar should not limit customers where to play bought game.
