I'm not sure why you're so angry about this. Amazon is clearly investing quite a bit of money in this, they've designed the drones, built facilities and a web infrastructure to support it, and they're actually running a pilot test. Maybe nothing comes of it, but I don't think it's all smoke and mirrors.
I also wonder why this bothers me, but so few others. Here is my attempt:
I suspect its 80% smoke and mirrors, and 20% real development. There is no tangible hard information about the Amazon drones, nor about the team size that works on it. In every video the drones are different. The movies are obviously entirely staged. Sure, there are competitive reasons not to give detail, but there is nothing technical we have learned until now. I have found no conference paper, no public industry-university project, no credible info other that some carefully staged interviews. I have no doubt that a hand full of people are working on this at Amazon, and that they build some drones and tinker with the infrastructure around it. And there are a whopping 2 people in the pilot project. That is a few million bucks investment, which easily pays for itself because the hype is used a a free advertising vehicle. But it is not nearly as it it suggested. I would be happy to be proven wrong. As a model airplane enthusiast and hardcore engineer I am dying to learn details!
Future applications of delivery drones will at best be very limited, but the general public gets the impression that its almost there thanks to this fake news where. How will they distinguish that from self-driving cars that are real? The difference is that there is abundant academic literature on self-driving cars, there are conferences on the topic and I see the google car driving on the road. Not so for these delivery drones.
What is the harm? It is just entertainment and perhaps it will just work out? Just like our political climate is polluted by fake news, so is the understanding of technology by the general public. People will believe that solar roads are real, and they believe the drone delivery , and soon flying cars... We move to a post-fact world otherwise.
I think this tech-trickery is on par with many classic skeptical hot-buttons. The main harm of homeopathy is not the health risk. Its that people waste limited money, time and resources on misguided stuff made by marketing spinmasters instead of engineers. Homeopathy is really not that different with fake tech such as this or Elon Musks'
hyperloop. It all seems to demonstrate well at first sight, but fails miserably in practice.
