Oh but it IS the problem with the provider. Or rather, it will be when some crazy PR storm hits the interwebz with "$YOURCOMPANYNAME leaked passwords!" when someone comes up with some clever way to hack/manipulate traffic with XSS or something. I was able to fetch private authtokens of a Wii game because port 80 was open on one of nintendo's servers(I assume it's there to test in plain text and just didn't close it later) and I was able to fool the software into using port 80 instead of port 443. That wouldn't have worked if port 80 was closed.
