The article states straight up that Win32 is used in way too many applications for Microsoft to ditch it wholesale in the foreseeable future.

What they can do is tweak around the edges to make Steam perform poorly and theoretically make the Windows app store more appealing, but that got a little bit tinfoil hat for me. I won't say it's unheard of, but they've already been under investigation once for these kinds of shenanigans and it doesn't look like we're going to have a friendly administration come in to pull their feet out of the fire this time.

Whether Sweeney is right or not, this whole discussion illustrates exactly why it behooves everybody (except Microsoft, I suppose) to switch to an F/OSS OS like Linux or a BSD. Everybody is trying to make their platform a walled garden, and the "war on general purpose computing" still rages as well. Using an F/OSS operating system, and open hardware platforms as much as possible, is essential to keeping computing open to everyone.

With more and more games coming out for MacOS and Linux I think there is a good chance that gamers would just jump ship. People are incredibly invested both monetarily and emotionally in Steam.
