Title and stuff.
Can't say I have much sympathy. It was Gizmodo's attitude that irked me the most about it.
If I found that phone and understood what it was, knowing that a fellow engineers career might be hanging on getting it back, I'd go to fairly great lengths to get it to him (if somehow I had already magically missed the easiest and most sensible option of just giving it to the bartender, of course). So I can't see the finder as having anything other than blatantly nefarious intentions.
Gizmodo's claim of anything resembling intelligence or professionalism went out with them bragging about how they bought it.
If the finder had said he made at least superficial attempts to return it himself and, failing that, handed it over to a Gizmodo "journalist" on the pretext he would be interested enough to use his industry contacts to get it back to its proper owner, and maybe get something to write about along the way, then everybody would have a reasonable claim at innocence (nobody has to know about the envelope of $50's). Instead, Gizmodo doesn't only come off as acting ethically dubious, but as being almost comically inept at it.
