a perfect example in this context would be when a company is successful and it's attributed to culture not product market fit, funding or luck

I understand your point about misattribution but it cuts both ways. How about when a company is better than competitors because they executed better because they had a superior organizational culture. Or not successful and this is due to poor culture.

YC sets the prime examples. It is never product at the expense of who the team is and in what proven way they have worked together and plan to execute at scale.
