It's possible this is a distinction without a difference, but Disney and Netflix provide a service and the data they are selling is integral* to providing that service, meaning they're going to have that data regardless. If you're okay with anyone selling any of your data, it probably makes sense for Netflix to sell data about what you watch on Netflix.

Samsung or Sony sell a physical product that does not need internet connectivity, or microphones, or telemetry, or any of that. They jam that stuff in there to increase profits and make it economically infeasible to sell what I think 80% of people on HN would buy if given the opportunity - a large flatscreen TV with no built-in connectivity whatsoever. So anything I can do to make me less profitable to them, I will do.

* For certain definitions, anyway.

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.
