Derived user data is still user data?

Up to the point where the client sends something mathematically indistinguishable from random noise to the server. At which point it's useless except for yet-to-be-discovered quantum effects. Which will then be outlawed.

Either way, the whole advertising revenue model is sickening pile of "they technically didn't object and it's not technically illegal", luckily it will die along with DRM and copyright. In the meantime I sincerely wish all parties who profit from it a stomachache proportional to their standard of living.
