If I were a CEO of a technical company and my company did a major change, say switching release strategies or adopted microservices vs monolith, these type of global metrics could indicate the benefits, or a problem. I agree that drilling down on individual people or trying to optimise blindly is the wrong move, but I think you're taking too much of a negative view on this. Shitty people will use more powerful tools for their shitty purposes, but that doesn't mean we should keep our tooling crappy.
