In fact, I think we are about to enter an era where our personal devices not only don't work exclusively for us but instead work explicitly against us. It will take a while for governments to gather some experience, but I won't be surprised when data gathering becomes mandatory.
Wouldn't it be great for instance, if police could just tap into Alexa's records to clarify a case of rape? Or throttle down your intelligent thermostat because you are wasting so much of our CO2 budget? Or stop your car because it already entered that particular city twice this year?
