> Engineers have very little say in what to build.

That entirely depends on the company. In my experience, the higher the quality of engineers a company hires, the more influence those engineers have.

I think my point has been missed. You don't need that much manpower to maintain CDN. They have to either be working on something new, or sitting around doing nothing. I'm assuming they are not doing nothing so I am wondering what their product people have them working on that could be so inconsequential as to not be having any effect on their loss of market share.
