Honestly, after looking through the "apps" they created and what little I could find about reviews for them, I am having a hard time not feeling that Apple was in the right here. On the other hand, I certainly understand that having your business shut down with little or no notice and right of appeal lies with the "prosecution" can feel crummy.
If you're going to say that, I think you need to explain why you feel like Apple was in the right. This sort of vagueness and ambiguity is extremely unfair to the accused, and this is notoriously what big tech does (and I think it's wrong). What is it about the apps that you feel either does or should violate policy?
OK, using the article's words, let's count the ways:
Within 10 days, we updated each of the six applications: removed all rating requests, revised all payment screens in line with Apple's recommendations, added Intercom for swift user assistance, established a help center with articles on canceling trials, requesting refunds, and implemented subscription management directly within the applications.
6 apps * ~5 fixes = 30 problems ... they knew what they were doing
