one of the mentions that you added to your post (along with thelinuxEXP for some reason) makes it appear in a Lemmy community that's focused on Linux news, not screenshots.
then it's worth mentioning that only the manager (and possibly the modifications) are open source. the Spotify client it installs is still closed source. same deal as with apps patched with Revanced.
According to these new numbers from Valve, the Linux customer base is up to 1.96%, or a 0.52% jump over June! That's a huge jump with normally just moving 0.1% or so in either direction most months...
so I assume it was at 1.44% in June, which means... like a 35% increase?
such courage
