And thus, if it's not a good fit for you don't use it. Not getting into another long discussion here.

My only grumpiness (targeted primarily at the article from OP) is the idea that the Linux community is supposed to be handwringing about the fact that more people don't use Linux.

I would love more people to use Linux. MS and Apple are both in their own respective ways bringing all the worst aspects of profit-over-all into an area that used to be and should be about wide open spaces, experimentation, and learning. (shakes cane)

You can lead a horse to water, but you can't make it drink, and I stand by my assertion that for the vast majority of people it's desire, not technical barriers, that prevent them running Linux. AND THAT'S OK, not everyone has to want the same things I want. But I don't feel an obligation to chase those people, and I don't think the Linux community at large should chase those people. The Linux community should be making decisions and providing tools that Linux users want; it seems ludicrous to focus on the wants of people who don't use it at all.

Without taking the time to go through the specific Twitch top list, I'm still very doubtful that the gaming side of things is as dismal as you state, given my very positive experiences gaming with Linux in recent years. Regardless, your litmus test about running software not designed for it remains a metric that is useful for disqualifying Linux if that's what you want to do, but not a useful metric for assessing the success of Linux overall.

Edited to add: I use and support Windows on the desktop and server for my job. I see firsthand the things that suck about Windows, and they are certainly no less than the things that suck about Linux. Living in Windows 8-12 hours a day has not once made me regret my transition at home. Each successive Windows version since I left it in 2007 has served only to reinforce it.
