It's a bit strange because why purchase from Apple but then complain? If the quality is below the expectation; and/or the price too high, people can choose with their money to purchase something else. Viewed more objectively most people probably don't consider this to be a main impetus for people abandoning iPhone. I have not purchased any apple-specific hardware, but to me it is strange to e. g. make Apple big (by purchasing their stuff) and then assume there would be many people who are angry at Apple. That does not appear to make a whole lot of sense.
