That's a good point, but I guess for non-tech people activity => work and no activity => no work, so at that level it illustrates reasonably well, no?

Measuring activity, where by "activity" we mean "commits", means that a person who mentors other people, reviews thousands of lines of other people's code, and discusses that code in depth during long hours of meetings, does completely no work. I think you can see where such a measure can lead to.
