Peace, the most-downloaded content blocker for iOS 9 has been pulled from the App Store, not by Apple but by it's developer, Marco Arment himself.

As I write this, Peace has been the number one paid app in the U.S. App Store for about 36 hours. It’s a massive achievement that should be the highlight of my professional career. [...]

Achieving this much success with Peace just doesn’t feel good, which I didn’t anticipate, but probably should have. Ad blockers come with an important asterisk: while they do benefit a ton of people in major ways, they also hurt some, including many who don’t deserve the hit.

I totally understand this feeling. No amount of money can make you feel great about being known for something you don't fully believe in. I bought Peace and like it quite a bit. The lack of fine-grain controls do bother me a little, and I may switch to one that is better in this regard, but I don't regret my purchase at all.

Additional kudos to Arment for explicitly stating how to request a refund in his post.
