This means there's some switch built into the code that changes its behavior, either after a certain date, or on certain known IPs that Apple tests on, or after a certain URL changes value.

At this point, the complaints pour in. People ask for refunds and claim it's not as advertised. The $400 subscription fee has to be mentioned in some complaint.

And at this point, Apple falls flat on its face. It does not investigate any of these serious complaints, which are easily validated.

Apple is one of the most profitable companies in the world. If they can't afford to do the right thing, they shouldn't run this fake "walled garden" app store. If 30% of my app dollar goes to them, an app that doesn't try to steal hundreds of dollars from me is a very very reasonable expectation.

For example, if the app reviewer’s touch interaction with an app were recorded and the resulting screens diffed with the same pattern after publishing, there should be no changes.

This is a method used as part of some UI testing with selenium.

There could be apps this does not work for, such as when content changes or conversion type UI is shown.

But I imagine there is some amount of low hanging fruit here. And even that once a “scam” app like this one is reported, Apple should want to review past diffs to look for the example of the violation.

I also agree that for the price, this is what apple should be preventing on behalf honest developers

It is also worth noting that DMCA is embraced ITT whereas with Github’s response to DMCA recently it did not get the same treatment.
