This makes a lot of sense when you think about it. Apple puts almost no effort towards building low end phones with thin profit margins. It's a huge market that has to be filled by other vendors.
> BMO Capital Markets analyst Tim Long estimates that Apple accounted for 103.6% of smartphone industry operating profits in the third quarter. Its share is over 100% because other vendors lost money in the business, resulting in Apple having more smartphone profit than the industry netted overall. In the year-earlier period, Apple grabbed 90% of smartphone profits, Long said in a research report Thursday.

It makes even more sense when you realize it's volume that triggers anti-competitive laws.
