Any IoT device (Internet connected "thing") has the capability to spy and share the data passing through the device to anyone controlling it - including the device vendor.
If it has a camera or microphone you should always presume you are being spied on. Whether that data leak will be (ab)used or being even remotely interesting is not an important detail. The important detail is that such devices is disturbing your privacy at all times, even in the most intimate moments of your life.
Whenever I am in a room where I'm aware of such devices, I always tend to think twice before sharing my opinion. That is the chilling effect of this.
We are literally living in the world George Orwell described in Nighteen-Eighty Four. But he lacked the imagination of cameras and microphones being in all kind of rooms and devices; not only the telescreens.
And yet the world craves for more interconnected services and devices. It's dystopic.
