> Home no-business-use-case (mostly gaming and maybe light web browsing) PC owners, and I suppose x-box? The former has got to be negligible at this point

With the broader job market being not-great, and everyone trying some sort of side hustle with the aims of making it big, it's definitely the bubble I'm in, but the "home" case has a lot of Google free office suite business looking usage, and even if there isn't a side hustle, maybe my friends are super weird but they use Google sheets to organize things even for non-business life things when things get complicated. Eg planning a wedding. That's Google and not Valve, but if customers get Steamboxes to access that vs Windows laptops (or Chromebooks), it looks like a threat to Microsoft to me. (But it's been the year for Linux on the desktop for decades now, so I'm not holding my breath.)

You should check out the adoption curve for Linux desktops, it's actually starting to hockey stick, Windows 11 is a dumpster fire, Apple is stagnant and Arch based distros are getting crazy good.
