I wonder if part of it has to do with the expectation (and common practice) that the photo will be shared, whereas the other data is often not shared or at least not shared publicly? I don't know. For me, the photo makes it a discrete moment that I can identify, more tangible, compared to my ISP silently recording every website I visit. I think there are probably many reasons why. I actually think Apple's new commercial for privacy gets at this well, where it has people literally following someone around and snooping on them, asking questions, and I think that visceral surveillance may few much more intrusive than the hidden forms.
