This is nonsense. It was perfectly reasonable for Apple to terminate Bogdan's (the Kapeli dev) account. This doesn't mean Bogdan did something wrong. What it means is Bogdan's relative, who controls the second linked account, did something wrong. And Bogdan shares some responsibility because he set up that second account (Apple did not link the two accounts incorrectly).

And the fact that Apple's willing to work with Bogdan to unlink and reinstate his account also does not mean Apple did anything wrong. If you actually listen to the phone call the Apple rep makes it very clear that Apple believes they were correct, but that Apple is willing to offer Bogdan a way to fix things.
