What? The $100 fee has nothing to do with that, and everything to do with the review process. Like, do you seriously believe that makers of all the shitty apps out there can't come up with $100??

Also, Google developer account used to be paid at one point. I have no idea if it still is but when I used to publish in the early days there was a fee to pay. Didn't stop the shitty apps from appearing because....that's not what the fee is for.

The Mac App Store had weird Chinese clones of Bonzai Buddy on it, but with different animals.

Have you SEEN the top 100 grossing on app store recently?
