I'm not really clear what you are showing me here? Nobody argued in court that Amazon was price dumping. It is speculated that the NYT BestSeller deal of $9.99 was maybe in that direction, but nobody really argued that in court. Quite the contrary, it was argued, successfully, that it was perfectly legal for Amazon to offer discounts like this. (Ironically to this debate, they didn't blankly sell all ebooks at 9.99, and no numbers were released to indicate how many were sold at the publisher suggested prices. As a customer at the time, I know I bought many NYT listings that I wouldn't have bought otherwise, thanks in part to that being a very low friction price.)
More, your argument was that sales of physical books were impacted. But, to show that you would have to be able to actually show it. With book sales continuing to climb, that will be hard to say "but it could have been even bigger!" Indeed, most evidence is that the ebooks were additional sells.
That all said, and I quote your article, "In a major rebuke, a federal judge has ruled that Apple violated antitrust laws..." Again, the point I was raising is that antitrust is more than just monopoly laws.
You can try and argue that the case was ruled incorrectly, but Apple was unable to do that with probably some of the best lawyers that you can get. Appeal was struck down and they were guilty of antitrust. Pretty convincingly.
