Free Windows 10 support ended for most people this past month, and the trend line of Linux usage has been quite clear leading up to this, as people prepared for the inevitable. An increase in Linux usage is also correlated to a drop in Chinese players, which did happen this month a little bit, but Linux usage is also trending up when filtering for English only. It’s worth noting that for all the official support Macs ever saw in gaming, they never represented anything better than about 5% of the market.
Tbf, I think people are hoping for mainstream SteamOS as the “safe supported option”, because they are afraid of an “unintuitive experience” (This is basically a Linus Sebastian demographic problem).
Personally, I think that’s a bad judgement call (as platforms like Bazzite have already proven that an official SteamOS environment isn’t required to have a good time gaming and using your machine), but I guess that means there’ll be even more excitement once that releases.
