It's definitely a niche market at the moment. It really shouldn't be given the implications of connected devices, sensors like cameras and microphones, and where those devices get taken by many of their owners. I believe we would have a much safer and more resilient society today if the norm had become for connected devices to follow the principle of least privilege and for there to be complete transparency about how any kinds of sensors and any kind of remote communication operated. But apparently the market has spoken (even though in most cases it was only given one "choice" of what to say).
