These kinds of surveys are notoriously unreliable. There is no way for the interviewer to verify, no penalty for the participant lying, and you're talking to a complete stranger over the phone, further reducing the barrier for lying. There's also possibly a motivation to "send a message" to FB such that they improve their policy without the interviewee personally having to pay a price. Would be amazed if even half the "yes" responders actually did. Wouldn't be surprised if literally none of them had. Probably the best way for most people to "resist" would be to block FB tracking, and anyone who sells it to them, at the browser level. If enough people did, that swing the "materially hurt FB" vs "keep my personal utility of the platform" balance into the positive. edit: to clarify I meant the respondees lying.
