Amazon's a big boy, and they're obviously acting in what they see as their own selfish interests. And those interests aren't mine, given I've never bought an ebook through Amazon, and have no interest in doing so.
It's just that I don't trust the statements of publishers. Maybe I've read too many stories of authors being screwed by their publishers, and I have a cockeyed view of the situations. But, I'm a skeptic when it comes to a publisher's statement. So I poked around, and tried to see if Macmillan's claims are consistent with their actions. And their actions involving the publication, format, and pricing of

seem inconsistent with their statements.
