> Facebook doesn't want these companies sending users' personal data to them without their knowledge Facebook's claim about not wanting the data is contradicted by actions. They chose to make their SDK send[1] analytics signals on library init before the user could have even been presented with a request for consent. They chose to have their analytics SDK send[2] everything to Facebook by default, requiring developers to go out of their way to disable the spyware (including somehow discovering that this step is needed). > Now if Facebook were to use this data for their own purposes, What would Bayesian analysis say about that question given a history with multiple events where FB et al were using the all of data they received however they want? Facebook lost the benefit of the doubt a long time ago, and it will take a lot of work to rebuild their reputation.
