Looks like everybody who purchased the content blocker Peace will be getting a refund whether they want one or not.
This is so unprecedented that I wonder if internally Apple is really pissed at Marco. Safari content blocking extensions are a big feature in iOS 9, and for one of the most prominent iOS developers to pull a top grossing app because it "didn't feel good" doesn't really paint the new feature in the most positive light.
It will also be interesting to see if Marco posts another App Figures screenshot once all these refunds go through.
