"The Justice Department has sued Apple and the publishers not because the agency model is illegal—it is not—but because Apple and the publishers may illegally have conspired to adopt the agency model to restrain Amazon from creating a monopoly by determining its own pricing.

But what seems inevitable is that this tangled web in which the government helped give Amazon a possible monopoly, will be chuckled over by law students and their professors for many years."
