The "they will get punished" is a bit extreme. Big corps have both teams trying new things and maintaining existing ones. The proportions vary widely, but things get tired and fail all the time. If people get fired over trying something, that would make a very dysfunctional company. The budget for validating if they can stop some stolen deliveries would not be worth mentioning in most meetings.

Although I haven't been in Amazon specifically, in my experience in corp, the worst that happens to bad mid-level managers is that they're moved to a different project. And that's actually overall bad managers, not someone trying out an idea.
