My thoughts
How long before these devices fall under legislation so that companies can be compelled secretly to give access to them, so that without our knowing government bodies can request they access to private conversation in the same manner as phones etc.. under the guise of anti terrorism or crime prevention.
I don't consider myself a conspiricy theory nut, just a person who believes in the right to privacy, right to anonymity and that anti-terrorism/crime-prevention is inssuficient reason to invade those rights for an entire population or a minority. It is fact that similar powers have been abused since governments/agencies have had them and those against the idea treated with contempt so there is no reason to expect them to respect us or behave should they have even more tools in their arsenal.
The very idea that a government considers it ok to limit a persons ability to protect their thoughts/privacy by demanding encryption keys or limiting encryption is frightening. I wish we had more brave politicians to stand up for us.
