DNS exists for more than just http and email too. I reckon you should learn more about how the technology works before telling other people how to run their lives and dispose of their private property. Or maybe... Just don't do those things at all.
I'm sorry to hear that, I hope they have better luck hiring in the future.
Why should someone have to serve http explaining to you what they're using their domain for? Why can't someone just have a domain for email and SSH and be left the fuck alone?
