They obviously chose not to offer end-to-end before, but now they can't even if they wanted to. So it's a distinction without a difference. It's open by default.

The media coverage was very "sky is falling" but the reality is that it only requires you decrypt content to which you already hold the keys or to which you can obtain the keys without compromising the security of untargeted users.
