It seems like a pretty clear duopoly to me, Apple and Android are the only two mobile platforms, and rather than compete with each other on price they are just both leaving their cut at 30%. Personally it’s not even the 30% I mind so much as, maybe there are cool new products like new mobile browsers that are just forbidden by the app stores and so we will never get them.
You can’t claim poor market share as evidence. If iOS and the Play Store are “good enough” for people to not seek alternatives, and for devs to still publish apps, then 30% might not be a big enough cut.
