For every site I use regularly, I have a one- or two-letter shortcut. When I want to use Slashdot, I hit ^L to focus the URL bar, type the letters sd, and then hit enter.
If I wanted to use Slashdot with HTTPS (which I don't), I would simply change the URL associated with that shortcut to say https instead. It would be zero extra letters for me.
(Of course I don't run a secret email service.)
Exactly what someone who runs a secret email service would want us to think!
I didn't mod it down, but it's at least partially nonsense, and obvious nonsense at that. Ask any linguist why English stopped changing 20 years ago and they'll laugh you out of the room.
Where are the calculations that go with a calculated risk?
