I saw the blog post about Mark's new protein powder and read some of the comments on the thread. There are a variety of positions on dairy in the paleo/primal world...but since it is controversial, why not use egg instead of whey protein? Egg is definitely paleo/primal, and perfectly healthy. Perhaps it is more expensive to create?
I often have wondered the same thing about protein bars. There are NONE out there on the market made with egg protein! Mostly whey & soy.
