2% (linux, really 1% steamOS and 1% other linux) and 1% (macOS) makes it sound much less impressive than "2x".

The options for an average user, who does not use steam and is not in the steam hw survey, are just macOS and windows.

The options for a serious gamer who uses steam (a tiny fraction of PC users) is clearly just Windows or SteamOS at this point, or more likely Windows + a steam deck (which is half of the 2% there, SteamOS).

Or just gaming on iOS / android, like most gamers do these days. The steam hw survey isn't really representative of gamers since the vast majority of them game on consoles and phones.
