I think what people fail to realize (when they downvoted my comment) is that it is common for companies (based on my 30 years in business) to offer special pricing to groups but not enforce that in any way. This is much different from pirating. This is "look the other way". An example of this is Apple's educational pricing. You can get this by presenting a student id of anyone in the Apple store and you get the ed discount. You can also buy from the Apple website and simply choose a school and get the education discount on applicable products. So ask yourself why they don't police this better? Because they don't have a problem with anyone doing it otherwise they would. But they aren't going to advertise it and I'm sure an Apple salesman won't tell you about buying this way.

Why? Well another reason is it's lets them get more money out of companies. So in other words they are allowed by law to charge different prices to different groups of users (by the way why is this fair?) So they set it up as a discount to some users rather than saying "we are going to get Boeing for more because we know they can pay more".
