I don't think it was self serving either. I'm just a big advocate of charitible acts being done quietly. I agree that the intent of the post may have been one of "the company in which we have invested is contributing by sending cameras".
Regardless of the intent, it's a generous and potentially very valuable gift. It's quite possible that the cameras will not be used, but if they aren't made available, it becomes a certainty. I wish the biggest problem the searchers have is too many tools and resources.
