I do object to thinking it has precedent. This is a new situation that is going to get bigger with iot.
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.
I don't know why you say this, though, when you are arguing that I should be.
> because you are somehow related to the data you get ownership.
In the absence of a compelling reason otherwise, I demand such ownership.
I don't see that data as anyway owned by you, you might have rights to aspects of it, but in no way can you demand ownership over something you don't own.
Because it is data about me that I'm generating personally, on my own personal equipment. That data is literally nobody else's business unless I choose to share it.
The notion that it's OK for me to be forced to send such data to others seems extreme to me.
