> No, It is Linux's severe failure that it lacked a singular, stable, and unified userspace GUI API.

Careful, some people are too hell bend on idealogies than making a reliable product. They'd never understand this.

This is one of the reasons why open source (free as in beer) will never work for anything serious. When my work depends upon a software someone made for free, there's an unnecessary power dynamic in play where since I didn't pay for it, they can rugpull me anytime. Before someone comes with the argument of forking, that's not how an economy works. I can't be the farmer, the truck driver, the salesman and sometimes even the buyer at the same time.

The kernel doesn't owe anything to the distros, which is insane, distros doesn't owe anything to the various libraries and vice versa, none of them owes anything to the application developers. It's a boat where each person is rowing in their own direction because they don't care what others does with their code and they don't have to. Because they are working for FREE®.

The effects of this is catastrophic. Everytime I try to switch, I can't find a single userspace application that works half as good as windows applications. People need incentives to make their work good, no one does anything for free. Free just means it sucks.

If microsoft/apple/google tomorrow releases their own distro, every single one will abandon their flavor of the week arch/ubuntu/mint/fedora for that one. One that's made by people in exchange for money. I bet the ubuntu developers use macbooks.

> The calculus is very very very boring and simple. Game devs will support every single platform on the planet in which the cost to support that platform - both directly and long-term maintenance - is less than the increased revenue that platform provides.

Companies end up not doing profitable things all the time, for many reasons. One rational reason is that while action 1 might be profitable, action 2 is even more profitable. So the fact that Linux is not supported does not show that it would not be profitable, but rather that there are other things the companies can use labour for which they think is even more profitable. If they could freely clone their employees (and "unclone" them afterwards) all profitable things would get done.

(This is just nitpicking about your economic argument, I have no reason to think your conclusion is wrong).

> Supporting Linux is a monumentally tremendous pain in the ass. Radically more than literally any other platform. It is hands-down the hardest and most painful to support natively.

Funny, I have the same feelings after 5 seconds of using MSVC or looking at Win32 documentation. Or is it WinRT now, or is it .NET Core, or .NET Framework, or UWP or OLE or COM, or whatever the API du jour is which will be slightly incompatible and incomplete with the rest of the ecosystem in poorly documented and inscrutable ways?

Performance profiling and debugging tools are critical for game development. What's your equivalent to strace again, the one that's built into the system natively? There isn't one?

All major game engines I am aware of support native Linux builds and have for years, anyways.

I guess there's a reason 80% of the servers in the world run Windows. Because it's so hard to develop for. Er, uh...no wait!
