It is very interesting to me that Linux desktop is beating ChromeOS. Not sure what the stats were 10 years ago, but I do not think MacOS or Linux were that high.
I blame Microsoft (as the root cause) for Linux's rise. Without the danger of games only being available through the Windows store, Valve would never have needed a safety - meaning we'd have no proton, no contributions from Valve, and no Steam Machines or the Steam Deck. I'll be the first to admit the former didn't sell well and the latter is too early to really count, but it's undeniable Valve's had a large, positive impact on Linux adoption.
Steam Machines/SteamOS, and especially Steam Deck has gained a big following from gamers which is arguably a bigger "home market" than Apple's creative professional home turf. Also I suspect ChromeOS might be losing steam as apple pushes back in education and windows 2-in-1s take back the low end market.
