And if you combine the revenue of all of those companies, how do they stack up?

To put it into perspective King (maker of Candy Crush) - just one mobile app developer made $2 billion in revenue last year (https://www.statista.com/statistics/288974/king-annual-reven...)

That's about the same as Autodesk (https://www.statista.com/statistics/416235/net-revenue-of-au...).

Having a dominance in a platform (Windows) with a shrinking market is not a winning formula. Why do you think Microsoft is de-emphasizing Windows?

From no less than the CEO of Microsoft.

At our core, Microsoft is the productivity and platform company for the mobile-first and cloud-first world. We will reinvent productivity to empower every person and every organization on the planet to do more and achieve more.

You just said games don't count.

I said games don’t count as far as a reason to care about Windows desktop dominance because “Windows” games are usually written on top of a cross platform framework that is fairly easily ported to another platform. Claiming Windows is important because of the number of Unity games that run on it is about like saying Windows is important because of the number of websites you can go to on it.

If that was that simple, we would already have the year of Linux Desktop Games, we don't and never will.

Yeah, I know about Steam on Linux, just a tiny drop of Steam on Windows.
