Yeah, with large companies like Amazon, never discount bureaucratic log-jams and just regular stupidity. I agree with you that optimizations can be made, but the system may be in a 'not broken, don't fix' local maximum. The inertia and complexity may be too hard to over come. Twitter only recently upped the character limit after nearly a decade because the old code-base was spaghetti and didn't allow improvement. But these are the reasons why the large CEOs have always been terrified of 'two guys in a garage'. They know they have issues like this, and that the little scrappers don't. If anything, these little issues are the camel's nose under the tent of Amazon.
