The difference is the target audience. When a company reaches a huge size, employees have an incentive to act nice internally, because that's the way to promotion; but they have no incentive to be nice towards external folks. It takes effort from management to ensure people act nicely towards others, and Nokia clearly failed at that.
I met one of their "evangelist" when they were trying to push Qt. He came to a iOS usergroup, so clearly in "enemy territory", and just used a precooked slide deck that compared Qt to Symbian - nobody gave a shit about Symbian there, but that's how they lived, stuck in their bubble. He was quite off-putting and way too commercial-focused for a tech UG; I already knew Qt and left thinking I could have done a better job of selling the tech.
What was it then? Were you in a customer facing role?
This wasn't clear from your original post at all -- you just said you had a lot of fun working there, not that you felt you treated customers super well.
If you were customer facing, and taking at face value you were wonderful to work with for outsiders, then yes, within Nokia you were a great outside facing person (and I'm sure there was at least 1 other in such a big company). But also with a lot of poor outside facing people (from the comments in this thread).
