Apple's feedback blows, and you clearly have never submitted an app to the store in order to know that.
Apples allowed these apps for 10+ years - enough to build business off of that feed multiple families - and then changed the rules with 30 days notice.
Conveniently, just coincidentally, this 10 year period came to an end as they developed a competing feature.
Try to develop a few apps and then you can talk about what "app developers" know about itunes terms and conditions. if you think Apple doesn't apply their rules as it suites them, you are gravely mistaken.
