I sometimes wonder if Apple didn't come up with this model of charging devs 30% even Google wouldn't have too. These companies often end up with similar policies. But that one greedy kid showed everyone how easy it is to leech off on hard work of devs (who are also to be blame as we happily agreed to this BS) and now it's a common practice.

If safari browser had a Safari store with 30% cut pretty sure chrome extension store would also be charging 30% instead of their 5% now.
