And I wouldn't be surprised if that Seattle dev manager got pressured from above themselves. But at some point, someone has to set boundaries. If that manager then got pissy about it not being finished, there's a few lines to be used. One is "I was asleep". Another is "Night shifts and overtime are not in my contract", or "I do not get paid enough to do night shifts".

And another one, "A lack of planning on your part does not necessitate an emergency on mine".

But here's what I think is going on: Amazon's higher-ups (the level(s) above these people) are intentionally making these managers put pressure on each other to keep them overworked and sedate. I feel like this is the case for a LOT of US work culture across a lot of areas. It applies to low wage jobs with a high chance of being fired as well. Keep people stressed about the short term and they won't have the headspace to worry about things outside of their sphere of influence. This allows the rich to get richer and the politicians to become more powerful (and incompetent).
