I'm not trying to defend Walsh's position, which is crap, but where he probably got it from.

He's so black and white that he can't differentiate between the guy you play a game with who's obviously hammered in voice chat and calls in sick and the guy who's coughing up a lung and doesn't want his coworkers to get it or to come in and make costly mistakes.

Whichever is the more common case he's going to treat as the only case.
