It doesn't stop there. The business model of cloud and streaming services is to charge the customer, and then sell the customer's interactions with the service to third parties (data brokers), who cross-correlate the information obtained with other sources to build very detailed individual profiles.

You would have to go lengths (throwaway identity, email, payment with gift cards, VPN, etc.) with each streaming service to effectively prevent this sort of tracking. And after that, you will still own nothing. Worse, the streaming company may even ban you for using a VPN, or refuse to play the content on free devices because DRM can't be enforced. It's complete madness.
