The most interesting part of this story to me - the guy checked the serial number of his camera by uploading a picture taken by that camera to an online tool, which I presume read that out of the EXIF tags. It was useful in this case, but it's still somewhat creepy that every picture some significant subset of people are taking includes personally identifiable information.

In what way is the serial number of your camera PII?

If there were a big enough set of images with serial number data associated to them, it would be trivial to link one image to another - which might be used as a profile picture on Facebook, or perhaps a picture on a dating site.

Being able to link the photos to the same owner could potentially lead to PII becoming available, and could lead to embarrassing, or potentially dangerous situations.
