You know what else isn't cool? Working at GitHub!

More seriously: I probably wouldn't have called every single current employee of GitHub a "loser", but more because I think truly cool people don't define themselves by where they happen to work at any given time. I'm sure the vast majority of people at GitHub are just tech employees trying to earn a living and don't particularly care whether the Zig guy thinks they're cool or not. What actually matters is that GitHub is a big centralized platform run by Microsoft for their own ends, and it's good to be free of it.
