MacStories:

Apple has since posted a clarification to the iTunes Affiliate Resources website that says:

“We’d like to clarify some changes being made to the Affiliate Program. Commissions for all iOS in-app purchases will be reduced from 7% to 2.5% globally, and all other content types (including music, movies, books, paid iOS apps and TV) will remain at the current 7%.”

Great news for sites and people that use the program.
