I've heard the argument used against any editor that's not vi (and once against any editor that wasn't notepad), and against the use of source control it's self - "cvs won't be on every machine, it's better to just learn to use tarballs and patch files." (Not joking)

Most people as a normal part of their job can indeed install software on their development machines. And those that can't won't even be looking at new software projects - what would be the point?
