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.
