I mean FB has a lot of information about users, have you seen how you are tagged in the ads ? Any private person can target any subgroup and we know that FB transferred this data to different companies in the past, the probability that some government somewhere that wanted the FB data does not have it yet (maybe a bit outdated) is Zero.
Let's assume you block all applications that are suspected of relations with CCP (no proof, no trial) this won't stop CCP just buying this data from shady american (or foreign) companies so it would be smart to fix the root of the problem(data collection and brainwashing)
