There is no time line correlations to support your theory but there are plenty for mine. SteamOS died long before Microsoft renewed interest in PC.
SteamOS never died so much as it never really happened. It's just vanilla Debian with a clunky controller UI bolted on that Valve itself recommends not using on your main PC. I seriously doubt Valve ever thought that it would rival even the popular Linux distros, but just wanted to get the ball rolling, and if the thing actually took off and sold, well, great. Valve has the money to burn and a decided lack of shareholders needing quarterly returns so that when Gabe has an idea he can play with that idea. But Valve doesn't want to be in the operating system business, they have Canonical, Red Hat, and several others to do that for them. Valve just wants to sell games, even their own games when they decide to make one.
As for Microsoft, MS has been trying replicate Apple's ecosystem for a while, and can't ironically enough because the relative openness of the platform compared to the iron fist Apple has always maintained is stopping them from walling off their garden. And then Valve announced that they were opening up a Linux store front after the launch of Windows 8, because Gabe hated flat design like the rest of us. And now several years later Valve announces that they are paying special attention to Linux that will not pay off financially for the foreseeable future, but hey, if you want to jump ship from Windows you can still play all your games because here's this new version of WINE(Proton+DXVK) that they've been funding for two years in secret that's easy to use and in a few years will just work once they really get the kinks out. Oh, and they REALLY helped out the AMD open source driver team(MESA is better than AMD 's drivers now). You're going to tell me that all of this did not alarm Microsoft?
Internet Explorer is no more. Edge is now Chromium, because they have this big damn E icon that they have to do, something, with. Because it's Windows and you have to have a big E somewhere on the screen that you never click when you're using Windows that you also can't delete. Oh, and Microsoft is now publishing it's own Linux distro. It's an IoT nightmare, but hey, it's technically Linux just like Android. Take a look around kid, Microsoft is now outsourcing the heavy lifting of it's web browser to Google since they know you're going to switch anyway. MS is outsourcing the kernel of their new OS to the Linux Foundation, and basically just copying Google's strategy with Android. Windows 10 has a Linux sub-system and it ain't there to run LibreOffice. It's a just a matter of time before Windows is some sort of bastardized Linux OS, similar to iOS being a UNIX operating system. The whole tech world is converging, which is not a happy thought for me, because once upon a time Linux was here to free us from the Microsofts and the Googles, but now those big players are planning to use it to build a prison around us.
