Wasn't it established that the whole sales spiel was geared towards criminals? If Yahoo mail was largely aimed at criminals I wouldn't have a huge problem with police having a look. Actual Yahoo has mostly ordinary people so I'm not ok with that, but this thing seems to be specifically for crime, no?
>Another network, EncroChat, boasted that its devices offered “worry free communications” and “the electronic equivalent of a regular conversation between two people in an empty room.”
Is that "geared towards criminals?" I can see how you'd say yes, but there are plenty of other people who would be interested in such a thing. It's also very similar to the sales pitch of any encryption protocol.
