On: GitHub threatens to shut down a repository for using the word 'retard'

[niuzeta]

Because "retard" may not be the last time, but the first. A precedence would be set that a repository may be shut down due to an arbitrary(not the word I'd use here, but for the sake of argument) reason.

Also, euphemism treadmill. "Retard" in the context of medication means that a drug is slowly and continously released into the bloodstream.

But that arbitrariness is baked into the user agreement and always has been.
