The fact that they advocate something called The Cyrus Murder. From the page notes: Note that Cyrus Murder is still relatively young in the grand scheme of things. I would appreciate it if we all worked hard together to make Cyrus Murder non-existent in the grand scheme of things, thank you very much.

It's certainly the first time I've see a program with the option

on it. I prefer to create relatively well adjusted program, passing the occasional
switch when the circumstances call for it.

This trumps my previous #1 reason for why I didn't go to CMU: the fact that it's in Pittsburg. Pittsburg bad... but not as much as Cyrus Murder I'm afraid.
