For a lot of people, a big scary warning page that says that a page is insecure is essentially a block. Yeah, you can still access it, but a lot fewer people will.

My original post is asking for an explanation of how it isn't secure. I would totally understand a browser warning if a user tries to submit a form over http, but for a page like the one I linked I don't see how it can adversely affect the user.
