This wasn't really about the fact that it wouldn't accept his name but about the message it gave him, which to me is a problem of letting developers write error messages. Why do we write error messages that sound like robots when spoken?
Maybe that is unfair to robots who speak the way developers programmed them.
Either way it doesn't seem like anything worth getting in a huff over. I don't think it was meant as purposefully degrading or had intent to insult. If anything it just wasn't clear enough; they meant - contains invalid characters for this system. Why take it personally? I don't think whoever wrote the error message was trying to make some sort of statement against "traditional" names.
