Huh?? If a streaming site (or any product for that matter) is free, the user is the product - be it their time, personal info, whatever. It is known and accepted that a “free” service will have a catch that allows the provider to make money.

If a user PAYS for a service it is expected that the payment is enough remuneration for there to be no strings attached. Of course companies will look for shitty ways to do shitty things to make more money, and those companies ought to be punished, generally by a reduction in customers, for their shitty behaviour.
