Good points. I think the thing that irks people is Apple's bullying. They just don't seem to be operating in good faith. For instance, from the report, here are Apple's "Anti-circumvention Policies":
>2. “Multiplatform Services: Apps that operate across multiple platforms may allow users to access content, subscriptions, or features they have acquired in your app on other platforms or your web site,... provided those items are also available as in-app purchases within the app. You must not directly or indirectly target iOS users to use a purchasing method other than in-app purchase, and your general communications about other purchasing methods must not discourage use of in-app purchase.”
Apple is dictating what I can tell my customers in "general communications" where Apple is not involved. That's not a free market, it's abusive. If a customer comes to my site from a search I should be able to say "Here are the purchase options. Please note that Apple takes 30% if you purchase through their store. If you purchase direct, our processing fees are only %2.5".
In that statement, I'm not making any judgement call on whether Apple is good or bad. I'm simply stating a verifiable fact. If the value proposition of Apple's store has benefits to the consumer then its merits should stand on their own.
For the record, I believe the App store offers many solid benefits to consumers. I'm just saying we should let the consumer decide if the benefits of the App store outweigh their other chosen criteria.
TL;DR Apple has no business inserting itself in my customer communications on my own website so long as I only state facts.
Edit: This is from the perspective of say, an eBook author or MacOS developer. I realize that iOS apps can only be purchased through Apple so the point there is moot.
