I don't know if that justifies using software that restrict peoples freedom.

I mean I make proprietary software for a living (as do, I assume, a huge fraction of people commenting on HN). For a lot of use cases I prefer proprietary to open. I have zero moral questions about using my iPhone or Windows desktop and I consider anyone who tries to use open software as a moral imperative do be fooling themselves and wasting their time.

With that out of the way I think it's completely irrelevant for the original discussion. Game developers are going to make games for the biggest platforms. So if you want to play the most titles, you choose the bigger platform.

Yes, so long as people keep using windows, the games will keep coming to windows . But I'm not going to waste my time crusading against that in order to maybe see Linux be a more viable gaming platform in two decades. Life is just to short. I'm not enjoying Linux on the desktop much to begin with, so in my case the game issue isn't really the deciding factor. For a lot of gamers it probably is, though.
