No competition from Amazon. Have we already forgotten it was a hoax?
Your link doesn't even prove that it was a publicity stunt, and here's why: its conclusions are based on false premises and it's full of fud. It's also clear why you didn't bother to link to the full article; it doesn't say what you want it to say either.
First FUD: "The practical issues are manifold". Yes, welcome to the real world. FUD, not a specific objection. The specific objections are then made, and they are stupid. "[...]how does it [the drone] then find the package's intended recipient?" Probably it homes in on the mobile device used to make the order, and you'll probably have to use one. How is the transfer of the package enacted? Depicted in the video. It knows where it's being delivered. What stops someone else stealing the package along the way? You mean, by shooting it down? Ah yes, this line item was expanded into two, for filler purposes. And what happens when next door's kid decides to shoot the drone with his BB rifle? The same thing as when next door's kid (the house has a child?) shoots anything else that doesn't belong to them. Except in this case, it's recorded by high-resolution camera.
Then we have an outright lie: The Federal Aviation Administration (FAA), which regulates this area, intends to make commercial drones legally viable and workable by 2015, but this deadline is all-but impossible No, no it isn't. It probably won't happen anyway due to lobbying from entrenched interests. But there's no reason why existing regulations can't be applied to commercial drones. The area below 500 feet is already available due to existing restrictions on civilian air traffic.
Meanwhile, Wired claims that Amazon's delivery model makes the drones unworkable, but that is just fucking stupid. It's stupid because Amazon has already changed their model partially to add more services, and there's no particular reason they can't do it again. Sort of like how Wired changed their magazine from having purple text on black backgrounds to having black text on neon green backgrounds to having black text on white backgrounds. Two changes, see? The drones won't be able to deliver everything in Amazon's catalog. It'll be small, high-value items often ordered by themselves by people willing to pay extra for rapid delivery.
In short, while it might well have been a hoax, nothing you have presented (nor any other evidence) proves it to be so.
