Maybe you don't like it, and you are fully within your rights to cancel, but it is not abuse. They can or should be able to carry whatever products they damn well please.
A truly customer-focused company would sell the products its customers wanted, even if they competed with the company's own-brand products. And demand for these competing products would be seen as a spur to improve their own.
I personally don't think the Amazon's talk of customer-focus is entirely marketing fluff, but I do think it's unevenly applied. Petty, anti-customer, monopolistic business practices have been a mainstay of the tech industry for years, and it's inevitable that they would infect Amazon to some extent.
Context: I'll admit to being a fairly rabid Amazon fan (no other conflicts, other than as a retail shareholder). I still cross-shop NewEgg (to support anti-patent-trolling), Ebay, Aliexpress and others, but Amazon wins more than its share of my purchase traffic.
Amazon's customer centric nature is generally pretty good, but they toss it aside at times. AIV on Android is one of those times (took them years to release the app and when they did it required a completely screwy install)
They're just shitstains
If you take that as the intent behind the quote then it's kinda parallel to the issue of whether to sell chromecast or not.
I thought that was obvious, and a charitable interpretation of his post would've made this clear, I think.
I asked about the Apple TV. After other lame "stocking" issues, a supervisor said "oh, we don't have licenses to sell Apple TV" and went on about how there's all sorts of legal issues.
It's vile for a company that's supposedly pro-consumer.
Amazon and Apple have had a long patchy history when it comes to selling Apple products.
Primarily it comes down to Apple's need to control the pricing of their products and Amazon's desire to drop prices far into the realms of lossmaking, which in part is due to their customer centricity. I cannot comment on this specific case but it is not always necessarily as clear cut as you think.
As an aside, the customer obsession is not fluff. It is deeply engrained within the business and is taken very seriously. Any decision that is not customer centric (e.g. Halting the sale of Harper Collins titles) is usually escalated to Diego (head of Retail) if not to Jeff himself. Any business is well within their rights to make money and preserve their self interests, and occasionally strategic decisions may well clash with the culture so not every decision Amazon makes will be perfectly customer centric. With that said, from both the inside and outside I've witnessed really great customer obsession on the whole especially when compared to other businesses.
