I had not read about this, signed in last night to get a message from my sister-in-law about Secret Santa arrangements for this year, and got hit with the prompt. It defaulted me to everything being public. I don't know whether I count as "anybody concerned with privacy" or not, but my understanding on Facebook has always been that when you Google for my business you do NOT see how long it has been since I broke up with my girlfriend. The fact that that would have changed if I was not extremely thorough at clicking my way through their roadblock was upsetting to me.
