Their point (I assume) is that any kind of comparison between metrics invites some level of subjectivity, and they want to make the raw data as easy to work with as possible. I agree with this sentiment (insofar as there should be at least one organization doing that), but I agree that their presentation of the raw data leaves a lot out in terms of what you actually get for your money and which organizations are good at it.

I'm going to wait a few months for them to flesh out their site before I criticize them too heavily.
