Cote's argument that there was no positive competition effect as the market was pegged to either the agreed prices or the lowest selling price, vs giving retailers the free choice to pick their prices in the wholesale model is misleading.
First, the only way the wholesale model works in Cote's world, would be if you couldn't sell all of the most popular and profitable titles at a loss (ala Amazon). If you could price books at whatever price you wanted but never below the price paid or a min profit of a few percentage points maybe. She glosses over the fact that by a vendor (Amazon) created a barrier to entry (I would call restraint of trade), to any other potential retailer, by selling at a loss where a retailer in this market would make a profit. In addition, it also precludes a competitor for getting into the e-reader product market for the same reasons.
You call it 'restraint of trade' but I looked into this and there's literally no evidence to support that whatsoever. Amazon sold loss-leaders, they did not operate at a loss entirely. Cote recognises this and states it explicitly, so your characterisation of 'wholesale in Cotes world' is totally wrong too.
Amazon's barrier to entry was that they offered very low prices to the customer, but still made a profit. Any company with a large sum of money that didn't mind making almost 0 profit could compete against Amazon, in fact Apple were in a pretty strong position to compete in my eyes.
It's different because exclusive content must be negotiated, and for example Amazon would be able to fight it. What you're describing here is exactly the price fixing conspiracy that was at issue. All sellers are pegged to the same price, if one seller makes it cheaper, all of them may sell things cheaper. There is therefore no motivation to reduce prices.
Apple was fully aware that publishers were trying to solve the 'Amazon Problem' so you can't plead ignorance on their side.
That link doesn't actually contain any sources, and it discusses only average selling price. Perhaps you should take a look at defence exhibit DX-434 or DX-449. Both show price increases despite the average falling.
Honestly you're just ignoring the evidence, even the evidence that Apple submitted, showing prices rise. You also straight up described a non competitive, anti-consumer market, but didn't notice. You really should try and approach this from a neutral perspective.
