I have practically no doubt that Alexa and others are malevolently spying on their users, I hate to argue their case but I would like to be able to buy one if I wanted to.

Should I be allowed to buy a vehicle without a clear view of my surroundings if I only intend to use it on private land? Should I be allowed to buy a recording device with no privacy features if I intend to use it only in private? Does the potential harm produced by the availability of tools without bells and whistles for public safety outweigh the desires of users who would gladly pay for the bare-bones version and use it private?
