On the contrary. I've spent much of my career in the conservative "enterprise" world... and outside of the HN echo chamber, most established companies aren't yet making heavy use of Google products at all. Largely due to the cultural disconnect being discussed here.
Sorry, but "We'll give you 12 months notice!" is still nowhere near "enterprisey". Try a decade.
I work in the conservatibe enterprise world, and vendors dropping services with much less than a decades notice -- usually, but not always, with a recommended replacement that they are also willing to sell you -- is quite common.
I think Google's problem here, inasmuch as it has one, is marketing and relationships, not substantive policy.
