So what's another good reason for Nintendo to not stock Amazon US with any hardware? Or for that matter what's a good reason Amazon US would have to not make anymore money off selling Nintendo hardware?
Amazon probably doesn't make money on hardware. Nintendo systems are commonly sold as loss leaders. I know for a fact that a big chain in my country sells the 3DS XL at a 10% loss, even now when it's brand new. I'm no expert on huge-store-economy and cannot say why they do this with every single Nintendo system. Seems senseless to me - I like to try to profit, even on hardware. But no matter what the reason is, it's sure to be about money in some way.
I find your argument that Nintendo had a history of doing exactly what I said in the past, but they couldn't possibly do it again kinda silly. As I stated before, my guess is just a guess based on Nintendo's past. It's been going on for months and not one single gaming site appears to give enough of a shit about it to actually ask.
I work in retail, and have dealt with Nintendo for almost 20 years, both as a stand alone store and as part of a big chain. My father has dealt with them since 1982. We have been the biggest Nintendo-seller in the country, and we have also been quite small. We have some experience with their relationship towards retailers and how it has changed over the years.
Seen in light of that experience, talk about Nintendo still "bullying" and "strong-arming" retailers is ridiculous. They're not always easy to deal with, but they are always no-nonsense, friendly and professional. The worst thing they do is to refuse to sell to you if you break the contract, or if you owe them money and don't pay. You seem to have a very strange view of the business, as if it's some kind of playground where people are good or bad and plot schemes and mischief against each other. "Acting like children"... gimme a break.
