Theft is a problem in factories all over the world. That is why many of them are fairly secure places. It is also why I have to laugh when people that have never held a job complain about security and strictness at factories. People have varying morals and often an attitude develops where they want to stick it to the man.
Beyond all of that we don't even know if this was stolen, it could be a defective item picked out of the trash. Or it could be planned seeding of information by Apple. Plants like these can fuel interest in devices in ways that normal advertising can't. Considering I'm sitting on the east coast it is hard to tell what is going on here.
