   … … … okay. Here's the explanation.

   - Apple's support article links to http :// appleid.apple.com
   - That doesn't exist. There's no server running at port 80 on that server.
   - There IS an https :// appleid.apple.com.
   - The https :// version uses HSTS, so if you've visited https :// appleid.apple.com at least once on the device, following the HTTP link will auto redirect you to HTTPS.
   - But no one at Apple Support has ever noticed this, I guess.
