I know the meme and it didn’t go over my head. OPs remark was either misinformed or poorly phrased. The meme isn’t “I seem to use Arch btw” and valve isn’t seemingly using Arch, they most definitely are.
BTW stands for Beta Testing Workshop, which is the "bleeding edge" version of Arch that gets released early. You probably want the stable, long term support version that only gets released very infrequently, like every 3-4 days.
FYI - the owner of this site, gamingonlinux, was a mod on the !linux_gaming@lemmy.ml community until they were caught abusing their moderator powers. Then they deleted their account and complained on mastodon that it's stupid design that mod logs are public.
