This is obviously the line where we disagree, and thats fine. You are arguing that you are happy to give your data to a company if its integral to the service they provide. My opinion is that if you are giving your data to one billion dollar company that is building an ad profile and selling it to 3rd parties, then why have scruples about giving it to another? The ad companies are getting your data one way or another, cherry picking a single device on your home network to ringfence against that seems crazy in my opinion.

The issue is the kind of data, no?

I also dislike that my data is being transacted willy-nilly by content providers, it's a very different ballpark when TVs have hidden microphones recording my house, screen capturing if I'm showing personal photos on the screen, and sending that data to the manufacturer. That's a much worse privacy invasion.
