I dunno, I don't see this as bias or as anything nefarious. When I read the headline, my first thought was "huh, that seems unlikely; I wonder if they are counting Steam Deck users in that".
Frankly I just don't see it as an interesting metric. "More Steam games are played on Steam Deck (+ desktop Linux) than on macOS." So what? Even though the Steam Deck blurs the lines a bit, I don't consider desktop gaming and console/handheld gaming to be directly comparable. Or at least, I don't consider comparing them in this way to be interesting.
Just as I don't think "Linux is the most used OS kernel on the planet" to be all that interesting. Ok, it's interesting in a certain, narrow way. Obviously its use in mobile/embedded devices and servers dwarfs its use on the desktop. If we want to compare "OS choice on servers" or "OS choice on mobile devices", that's notable.
But when we're talking about gaming, and we want to compare "desktop macOS gamers" to other things, the only other things I think are relevant are "desktop Windows gamers" and "desktop Linux gamers".
If Steam-using desktop Linux gamers were surpassing Steam-using desktop macOS gamers, that would be huge, important news! But a bunch of people buying a Steam Deck and raising the number of people gaming on the Linux kernel is, to me, no more interesting than saying there are a ton of people playing games on the Linux kernel because there are a ton of people who game on Android phones. Whoop-de-do, film at 11.
(Full disclosure: I'm a desktop Linux user, and have been for over 20 years.)
