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.
