How about the POV that if I buy the device, I decide what the device does? This is a fundamental property right. You may argue that the data created isn't "mine", but I would argue that it is absolutely my data if it is created by a device I own. The fact that someone else manufactured the device doesn't give them some sort of retained ownership once they sell it to me.

This issue is precisely why I won't be buying any IoT device that requires the use of a third-party server, which currently means any commercial IoT devices.
