Here's the point: We've all already begun to acknowledge the death of privacy. Most of us know that yes, we stand a chance of being recorded at any time, at any place. That's oooold news, Admiral Burrito. With this knowledge in hand, the point of contention is now, "How well is access to that information controlled?"
Consider Mr. J. Random Dork, in an Apple store, aggregating thousands of photos of strangers without consent, for his own purposes. He is showing people, by his own conduct, that he is not a very good steward of the information he is collecting. He didn't ask the subjects, he didn't ask the venue, he didn't ask legal counsel, he didn't even ask his peers. In fact he deliberately avoided all those responsible inquiries because he knew his project was objectionable to all of them from the outset. Directing anger at him is not "shooting the messenger". Once you're writing your own code, you've pretty much moved beyond the "messenger" role and into the "perpetrator" role.
