Amazon pulls an Apple by reducing its app store cut for some smaller developers - The Verge

But where Apple and Google reduce their cut of a developer’s first $1 million in revenue from 30 percent down to 15 percent, Amazon’s formula has a slight tweak: it’ll take a higher 20 percent of revenue, but give developers an additional 10 percent in “AWS promotional credits.” The idea is that if your app is using Amazon’s popular AWS cloud services anyhow, it’ll be equivalent to you keeping 90 percent of the money.

By contrast, Google is simply giving developers an extra 15 percent of their first $1 million.

Also, revenue isn’t everything: as Fanhouse argued when it railed against Apple last week, an app that’s designed to profit creators, not its developer, might make far more than $1 million in revenue and not be able to afford 30 percent of the money that changes hands there.
