It's interesting how charging money changes the perception of different practices. Like with your hypothetical PRO membership, when taking into account the data that FB collects on people without their input, by studying their network relations, sounds to me like a massive extortion scheme: 'If you give us a monthly fee, we won't disseminate this potentially embarrassing/damaging information about you that we got without your knowledge or consent'. But instead of doing that, they're just disseminating the information, and not even bothering to give you the option to pay to keep it private, since they know that others will pay more for it than the average user will. The free option is certainly more damaging in some situations, yet the paid option is the one that feels criminal.
