This misrepresents and skips over Apple’s great offence, which is why a bunch of others who don’t know the half of it are piping up with their comparisons to the PlayStation store etc.
The most egregious part of Apple’s rules, and the reason that online service providers have a special loathing, is that apps are disallowed from linking to, advertising, or even mentioning that it is possible to sign up/subscribe/buy/rent outside of the app.
This is why you won’t see MMOs like FFXIV through the App Store, and is why you can’t sign up for Netflix, or even follow a link to their sign-up, from within the app.
