That advertising is to developers. I'm baffled by why anyone would think that the general public cares what payout Amazon is giving to developers. To the general public, it's a free app.
Do you seriously imagine that members of the public are attracted to the Amazon Android App Alliteration Store because they think Amazon is a more charitable and supportive firm than Google, and shows greater kindness to the ramen-chewing developer? I feel pretty comfortable in asserting that the vast majority of people don't give two hoots about what arrangement exists between publisher and distributor. Do you go to the movie theater and decide to watch a Universal film because their producers are nicer than the ones at Paramount? Do you grade other products/services you buy by the providers' corporate social responsibility score, or the credit terms extended to their suppliers? Of course you don't. With a few exceptions (mostly symbolic) you are wholly ignorant of such things, and rationally so. You assess products and services based on whether they fill your needs at a reasonable price.
I don't run a whole lot of apps and as a result have not got around to using the Amazon store, but non-industry members of my social circle have mentioned that there's 'a free app every day' there. I suspect that if I asked what return they think this nets for the developers of said apps they would just give a me a funny look.
There is 'general public' and there is 'tech-savvy android users'. The former you have probably characterized correctly, but I suspect you are underestimating the size of the latter. As the grandparent mentions, if people are posting on forums to help support the devs, then at least some people are being persuaded to use the service because they believe they're helping the developers.
Many people do go out of their way to support independent musicians or indie game makers. It's not unreasonable to believe that there are people who want to help support small mobile development shops.
It is helping the developers. It is getting them a broader userbase than they would otherwise have by having it promoted front and center on the app store, and also it being free. I think it is pretty humorous people would assume they would just get free money from Amazon for this.
As these developers discovered, all a broader user base brought them was increased infrastructure and support costs, with zero uptick in subsequent sales.
"A broader userbase" that doesn't pay anything isn't "help" by any stretch of the imagination for a number of business models.
