This will serve me,and many others on HN as a lesson on how easy it is to fall for false information. I did read the related post yesterday and there were lots of emotions, mainly negative. Now I don't even know whether they take the money or not, so I'll put a question mark until proven otherwise for time being.
If you would’ve read comments in this post thorough, you would’ve found it most likely has to do with the payment providers and not apple itself, as there’s nothing apple can do in that case (other than pay the difference from their own pocket, but they have no legal requirement to do that). Thus it’s not random.
Apple reserves the right to keep its commission and doesn't attach it to payment processing issues. It can do whatever it wants, and we can only guess.
