I feel that in the past (present is TBD) Amazon under-indexed on developer experience, tooling, and infrastructure but I think it was caused by lack of investment, not lack of ownership. There's nuance between "Oh no, <shared_resource> broke, not my problem", and "<shared_resource> broke, I want to fix it but can't because <XYZ reason>". In my experience it's usually closer to the latter here.
