Google's lack of a rich enterprise cultural workforce consisting of account managers paired with a culture of sales and services for profits makes a great deal of enterprises nervous since this is how they're structured for business for several decades. This is where Google's partners that are more versed in such traditional, engineer-hostile come in, but then you wind up where massive companies start to rely upon maybe 1000-person companies that will be crushed by the onslaught of horrifically mundane, non-scalable problems endemic to a customerbase consisting of non-technical people and sub-par engineering talent as standard. These companies know that they can't use these smaller companies and are not run by stupid people (usually), so they have really little choice among technology vendors that make most of the HN crowd cringe.
