It's a drop in the ocean though, I'm aware there's is a little of that but if you look at revenues you can say that without being too wrong. The in-house stuff is mostly a function designed to enable customers better more than a way to squeeze money out of it. It doesn't even crack the billion dollars (it's around 300M last time I checked).

But yeah, I should have known that given the crowd on hacker news I should have protected my statement from the "actually..." crowd.
