There's a pretty major leap in logic, there. What does diversity have to do with talented, passionate engineering teams? Companies like Honda and Toyota have some of the least diverse engineering teams on the planet, and yet they have a well-earned reputation for engineering excellence.
You may want a company to take diversity seriously, and there are many others who feel the same way. But it doesn't follow that maximizing diversity is therefor an imperative for companies that want to have world-class teams. In fact diversity seems to be orthogonal to competence.
