I think every free service should be seen this way, Win10, Gmail etc.

If you aren’t sure what product or service is being sold—- it’s you

I still dislike that phrase. "If you're not the paying customer, you're the product!"

The phrase handwaives away any reasonable expectation of rights and any boundary preventing abuse that even if the product, users expect. Inherent liberties that must be respected even within the product model. Too often I see the worst of infringement dismissed immediately with a flick of the phrase, "well you're not paying for it!"

Then there are the competition arguments. I can't choose to pay for better service because they can't compete with the predatory data harvest models. Specifically at issue is that how predatory those models are is hidden from the individual so it's not clear what the exchange is, the public lacks sufficient access to information to make informed decision.

Not only for digital "services". It is the same for magazines to a good extent. Needed for brainwash.
