If Sperry-Rand and IBM are sharing patents then there are, by definition, two suppliers.
Who were working together, a scenario covered under the Anti-Trust act.
Amazon has maybe a third of book sales. (2012 figure showed them at 27%) That means an overwhelming majority of book sales are not sold by Amazon - no monopoly.
Since Amazon is not colluding with its competitors in these news, there's no trust (multiple companies working together to create a "monopoly"), either.
As for "basic economics," you're forgetting that the strategies of a monopoly are orthogonal supply and demand. If you have a very low cost product, and you've got a monopoly on the low-cost version, you can keep margins high and keep prices low at the same time. You can also dictate the supply. You can choose to flood the market (which makes money in the short term, but adds large downside risk if the market turns and you have excess capacity you can't get rid of without blowing your monopoly), or you can intentionally not fulfill demand.
You offered a scenario of low supply, high margins, and low prices as if they came together. An artificially low supply can increase margins, but it's not going to reduce price - the price may absolutely be low, but it's going to be relatively higher than it could have been if the supply was artificially restricted.
If it works this will probably result in permanently lowered supply (the way Royalties work authors would be paid less if Hachette's cut went down, permanently lowering supply), prices would stay artificially low, and profits would be artificially high.
Hachette still has the same number of authors and publishing equipment. "Permanently lower supply" may happen in the future, but you can't lay the blame on Amazon. It's the publisher's job to supply demand; Amazon is a customer of Hachette. (They pay money for goods)
If the market is not working then Hachette caves, Apple can't force the discount, and it's got a very clear case of monopoly profits.
You keep using that word monopoly. I don't think it means what you think it means.
