This is really fascinating.

If true, it suggests that big companies with huge teams that try to force the entire team into equal contribution metrics are creating stress that might not help the team, nor lead to fewer bugs (big surprise).

I've never been on a team which was set up to truly recognize the value different forms of contribution, like writing tests, or removing code, or simplifying it, or other things which would not count towards the hero metric presented here. As an industry we just don't think about alternative narratives to "let's make sure everyone is an equal contributor..."
