Or admins who don't want to spend a day or two to learn about selinux and implications of adding it, then a couple more days to actually implementing proper policy for the company and deal with all the things you did not expect at first.

In reality it's not a tiny amount of work unless you're dealing with a single server. It's not a small amount of information to learn either. And it can have pretty bad effects if you happen to cut off your access by accident. So no, can't agree with the clueless admins comment.
