Well, it depends on the context. I think it's a great idea -- I would have loved to have geotagging available for my vacation photos when I was travelling in Costa Rica, India, Hong Kong, and England. Would I post photos publicly with GPS co-ordinates attached? Not while on the road, but once it's historical information, absolutely. Would I be geotagging photos if I were on active service in the military? Hell, no.

The real problem isn't the geotagging, itself -- it's that it's largely happening (at least on phones) with the photographer unaware.

Of course, in this case, the real problem is that you have someone fleeing authorities, supposedly trying to maintain secrecy, inviting along reporters, and blogging about it at the same time. If your life is really on the line, as he claims, it seems a bit... careless. But then, it all seems to be a game, to him.
