Now I understand why almost no one uses encrypted email
As someone who worked as a pen-tester, security is almost ALWAYS at odds with convenience.Making better security less and less inconvenient is the name of the game. Even if 100% security would be as easy as ticking a box, though, the fact of the matter is that most people don't care and if it's not "secure by default", it simply will stay not secure.Maybe a synonym for "turned on by default" is "absolutely zero inconvenience or attention needed"
