Do you have a handy link to Zunger's criticism of Transparent Society? Sorry, my search-fu is weak this morning. Based on the quality of Zunger's other writings, I'm open to what he has to say.
In practice, the forced revelation of information makes individual privilege and power more important. When everyone has to play with their cards on the table, so to speak, then people who feel like they can be themselves without consequence do so freely -- these generally being people with support groups of like-minded people, and who are neither economically nor physically vulnerable. People who are more vulnerable to consequences use concealment as a method of protection: it makes it possible to speak freely about controversial subjects, or even about any subjects, without fear of harassment.
(A classic experiment which you can easily replicate is to change your profile photo to that of a young woman for a few weeks. Change nothing else, even your name, and see what happens to your interaction pattern. I've seen quite a few people run this test and the results are, shall we say, quite visible)
GamerGate is one example after another of why transparency has asymmetric effects. The worst-case consequence for members of the mobs is fairly minimal: they won't face social ostracism by their friends (who after all, support them), they are highly unlikely to be placed in any physical danger (the police will protect them), and their jobs are not likely to be affected either -- and if they are, they can find others. Conversely, the threats against women in the field were physical and real, and (as you'll see if you ever experience the real ability of local and federal law enforcement to deal with harassment and threat cases, for manifold reasons) there is reason to believe that they do not have access to adequate police protection.
(I'd mentioned the G+ link a few times in earlier HN comments. HN's Algolia search is one of the secret strengths of HN, and is a chief reason I comment here as extensively as I do: I can often find earlier mentions of some point and reference or expand, occasionally correct, those.)
(Zunger and I apparently each believe firmly in paragraph-long parenthetical digressions.)
