Then you don’t care about freedom and having control over your computer. That’s a shame. I think you should.
You have to recognize that having an open source almost everything except a single program (steam) is better than what windows is doing by miles, right?
But is that actually true? There is no source code for SteamOS 3. How do you know how many packages are proprietary? Even one nonfree package is unethical. People deserve to have control over their computers, I don’t care if it’s currently a little better than Windows.
You can’t win everything, steam is never going to stop being proprietary
This is irrelevant. We should still try to make the world better and fight the injustice. If gamers realized this 10 years ago, maybe we would have this problem solved by now.
The issue is not as black and white as you’re making it seem.
You can’t have freedom when someone is actively trying to take it away from you. We have to get rid of proprietary software. If we accept the abuse from those companies, nothing will change. We’ve been fighting this battle for 40 years now. Those companies want to give you an illusion of freedom, so that they can pretend that they are good. They are using the work of Free Software volunteers to build a prison for you.
Plus if steam wins, getting people to switch to fully open source operating systems will be a lot easier.
No, there is no Free Software alternative to Steam and there is no reason to believe that Valve will release its source code.
You are making an assumption that Valve won’t make their system even more proprietary. But why wouldn’t they if their fans are ok with this? They’re already abusing their power with Steam. Giving them more power will only make the abuse worse.
