"In a nutshell, Canon has to compete with Nikon and a variety of others. Adobe competes with … ?"
A good point, Adobe has no real competition especially for a suite of programs. There is always the chance, and hope, that another player will enter the ring, but they would need very deep pockets.
As to Canon, I think it is simply their culture, they are smart about keeping customers and spreading good will. When I was a Nikon pro services member I never used the service, fortunately I didn't have to, so I cannot offer any first hand experience on the matter. However, I haven't heard glowing things about NPS either. If someone out there can join the conversation with reviews of any of the other players, that would advance the conversation.
Happy Easter all! Remember, eat the ears first.
