True... although hardware probably has far higher costs. I found a site giving apple's net profits for 2020 at $64 billion. If their gross was $294B, that means their profit margin on average was 21% for their sales. If the app store is almost pure rent, and you are overestimating the costs of things like reviewing and it is only a few billion dollars to run, then it could have a far higher profit margin than everything else. Perhaps even 80 or 90%? If so, that $21.7 billion gross is almost pure profit and becomes something like a third of all their profits...
