The billions of dollars paid out does not disprove that at all. There are many articles, often posted right here on HN, of apps getting pulled from the app store for random reasons. Lots of articles about apps that push an update and then get removed from the store because they found something else objectionable that was previously approved.

A few tens of articles, about things which are almost always resolved.

I personally have had updates rejected, and then simply resolved the issues and resubmitted.

It’s simply false to say that apps are just pulled at any time.

You have allowed a few voices on hacker news to give you a false impression.
