Long time Linux on the desktop
user here. I don't feel Linux has become significantly better recently. It's more that Windows reached a new low that is just below the threshold for many. Also, Apple, what are you doing?
Mesa, the kernel drivers and Proton have all seen a lot of growth this past year combined with a bunch of garbage decisions MS has doubled down on... not to mention, enough Linux users in tech combined with Valve/Steam's efforts have made it visible enough that even normies are considering giving Linux a try.
