They want to ban encryption which doesn't have a backdoor. It's semantics, but the end result is to make encryption ineffective. Which is practically the same as a ban.
I disagree. Politicians love to leave things vague so they can argue they didn't break their promises later on. Getting politicians to specifically state that they will not do something is always a win.
