Though not as morbid, I would imagine "stepping over dead bodies" and "leaving teammates behind" is a rather common experience in startups as well, though potentially frowned upon (but even then, it would depend on the situation).
EDIT: I think I need to clarify, I'm thinking more that startup COMPANIES are like everest climbers, trying to reach profitability/success. And then we can similarly say "[The internet] is littered with dead, exposed bodies [of startups]"
