"As The Post has written, voice-based devices like Amazon's Echo and Google Home are always "awake," passively listening for commands to activate. ... Google and Amazon keep a copy of every conversation. Amazon has not disclosed how many times users have improperly been granted access to another person's recordings."
At home, I sometimes use bad language, talk bad about politicians and even say dirty things. I don't want them recorded.
I guess I shouldn't care. I have heard Alexa being asked questions and I kind of like it.
