On a related note, I noticed that it's a bit socially looked down upon to be privacy conscious. This is pretty much a 180 from what the public perception was 20 years ago.
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
Where I live, the exact opposite seems true. If you are an ardent user of social media, you are more likeley than not to be under a bit of scrutiny.
