That being said, I would like to see a platform for discussion from BOTH parties instead of blogposts with no real communication.
I can't imagine it would ever happen, it would make no any sense from the business point of view unless you build your image as a privacy-focused company (Facebook doesn't even try). For example Tim Kendall's testimony [0] paints a very bleak picture of the motivations behind strategic decisions made at Facebook. There is simply no reason to reveal your real motivation and it makes more sense to hide behind corporate PRspeak, except a few very specific issues where you could make a case a privacy violation was caused by a bug etc.

These risks should've been brought up during code review (if not when the feature was designed and specced) and there should've been an opt out added to the Privacy settings dialog.
