Linux overtakes Mac as Steam's second-most used OS, thanks to the Steam Deck
Biggest issue with targeting "Linux" is revealed in the Linux OS breakdown.  If you throw out the SteamOS, you are left with about 45% of the Linux users in the "Other" category (i.e. not in the 6 most popular linux distributions), compared to about 14% for Arch and Ubuntu.<p>There's plenty to disagree with RMS on, but he's absolutely right that Linux is not an OS; it's a kernel.
