There's a big difference between startups iterating, and giants like Apple. I think we all remember how they were excoriated on the Maps release, which certainly wasn't perfect. Because of their scale, Apple doesn't have the kind of flexibility that unknown startups do -- not just because of their scale, but also because most of their software isn't solely web-based, but is tied into software that is sold with hardware which is released yearly.
I agree that they have a difficult time with a lot of consumer services. But I don't think it's nearly as simple as the author suggests.
