By most accounts, dealing with Amazon is actually much worse for developers than dealing with Apple. By putting your app in the Amazon Appstore, you’re giving up a lot more control than Apple asks of us: you’re giving up the ability to set your own price and control your app’s description, among many other restrictions. By comparison, it makes Apple look almost… open.

A truly open facet of Android — the open-source codebase, minus Google’s apps — has enabled one company with a strong market position to step in, effectively close it, and make themselves the gatekeeper. And as gatekeepers go, Apple looks quite benevolent by comparison.
