While the specific problem he pointed out is relevant, the rest of the article is just speculative. Does he have any proof that parts of Google is disconnected from each other? He seems to have an issue with the perks of Google (really just perks of tech) and sort of seized upon this one insistence to expound on that and other things he doesn't like.
He's not talking about the perks but rather how it insulates Google's worldview to that of an 70% white, 60% male work force.
That, along with being bussed into work & having all your meals, medical, etc taken care of on campus limits their perspective of what other non-tech people experience on a day-to-day basis.
His argument is that Google tends to think up these ideas in their own space, but since they're isolated from what the average american that uses their products experiences - they have no feedback component that tells them they're losing touch with their customers.
