In a shock turnaround, Marco Arment has pulled his ad blocking app, Peace, from the App Store. Later on Apple also started refunding everyone who bought it on the App Store.

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 admire Marco's decision to step back from the ad blocking market. I wonder how many others could turn their back on a successful app?
