Does that harm Microsoft in any way?
It might have if it wasn't "just" G5's. What if they were prototypes? What if they were from a company under special contract negotiations with Microsoft? Not all people give a damn about their jobs or carefully consider what information is sensitive and what isn't. Microsoft is proving a point that shipment security will NOT be comprimized, and as a former security guard, I have to side with the company on this one (regardless of for whom the employee was working).
