As happenstance would have it, though, it was MY skill that got rejected that started the forum thread that he pulled quotes from. If you are actually interested in more details, I can provide them, but the point wasn't really about my specific rejection - it was that this has been an ongoing and growing pattern recently across the entire development community. These issues are well documented and individually enumerated (so as to not just be anecdotal, per your concern) on the Amazon developer forums, if that is what you're looking for.
Regardless, the title may be emotionally driven, but it is not sensationalist. They (the Alexa team) literally do not have a good understanding of how to run this app store. I think the context missing here is that we don't mean that in the sense of "we're angry because our opinion does not match Amazon's". We mean that in the sense that we (and every time I say "we" here I mean the Alexa developer community) has had to hand hold the Alexa team into doing even the most basic things just to get the skill "store" where it is now, because it has not been a focus of theirs.
