Everyone is fine with you being privacy conscious to some degree. It's when you start telling them that they should be too that it tends to get a negative response. I'd argue that this is why the GP succeeds in their B/C tests - because they made it about their own choices. In A it's trying to convince the other party of a position on privacy instead which is, unsurprisingly, a lot harder
