I don't think anyone's trying to justify the format. It's just that your complaints are a decade old. Everyone knows what a horror the format is internally.
From a technological view, the format is a travesty. From a marketing view, it's the closest thing to a de facto standard that there is in the commercial e-book market. From a technological view, Amazon probably should developed a new format, or better, worked from an existing open standard. From a marketing view, Amazon's use of the Mobipocket format at least gives the hint of a promise of interoperability in the future.
Personally, I'm willing to bet that to Amazon's target market, the ones who are going to decide if e-books really matter or remain a niche market, things like HTML, XML, OEBP, etc. are just strings of meaningless technobabble.
