WYSIWYG editors, what's really wrong with them?

I don't really have much of a problem with WYSIWYG editors. I can understand people who already know HTML and CSS using WYSIWYG editors for low paid or short deadline jobs to help. It's when people who don't know HTML and CSS using them to take the easy way out. Also when people claim to be able to code when they use WYSIWYG editors annoys me.

I also, like Salathe need the code I write to be laid out and commented (tabs and closing tags labeled) in the right way so I can read the code quickly and edit it.
