I don't see how charging ebook authors 15c per megabyte a buyer downloads (it can't cost AZ anywhere near that much) before calculating royalties could possibly be anything other than shady accounting. That's not just a couple engineers confused about the specs.

> Basically, of the people who wrote the tool, tested the tool, and used the tool, none of them knew exactly how royalties should be calculated

I really don't see how this is a valid excuse. "How the royalties should be calculated" is a lawyer's domain, an engineer should never have had anything to do with the decision, and any engineer who was tasked with coding the calculation without proper guidance should have pushed back.
