And I will note per several comments from other folks that while Amazon is muffing the corporate PR war rather spectacularly, they seem to be winning the popular media war. Almost all the reporting I've seen draws from the Kindle Team letter in referencing a price increase without explaining that there's also a low-side price of $5.99 which is a significant decrease, nor bothering to explain the dynamic pricing model.
That's lazy reporting, and factually incorrect on the face of it, but what consumers are reading and hearing is "Macmillan tries to raise ebook prices on Amazon." So Amazon's deliberately flawed, self-serving narrative is winning in the popular media.
