I get the sense from the tenor of Gruber’s description that this has been simmering for a long time, and that it’s about a lot more than the App Store’s revenue percentage. Everything from search results to upgrade pricing to functional restrictions have long been frustrations, but the long-term combination of inflexibility, lack of transparency, and perhaps a sense of condescension, seems to have stewed to toxic effect.
