Interesting how the numbers between “computer pros” and hobbyists (Steam Survey) diverge. Unsurprisingly for Steam gamers the Windows numbers are way higher but for Linux specifically Ubuntu is crashing hard since a few years from absolute domination to all Ubuntu versions + derivatives (Mint + pop_OS) combined barely making up 20% of the Linux user base whereas at Stack Overflow there’s a clear lead of Ubuntu over the rest.
Latest non-LTS Ubuntu could be high up the Steam Survey list but isn’t. The strongest general purpose distribution is Arch Linux.
