In my experience, that's much more common. Everyone at amazon complained about how bad the tools and systems were, and yet continually repeated the mistakes that were to me blindingly obvious. But they topped it off with extra special levels of stupidity: The vast majority of amazon's software ends up being written by juniors, and when they finally bring in seniors, they put the juniors on new systems and stuck the seniors with the task of adding features to the crap (because seniors are "good at wading into bad code").
