Without HTTPS, the content can be replaced entirely. Last time it was JavaScript that DDOS'd github. If you don't want to serve content over HTTPS, then you don't care what your users receive. Just delete the site and they all get 404's instead, since you already admit that you don't care either way.

If it makes you feel any better, HTTP without HTTPS was a mistake we all made together. It should never have happened.
