I spent $2.99 yesterday to buy the Peace adblocker. Today, I find that the maker of the app is "conflicted" about it and has pulled it from the store.
He provides a link to how to get a refund from the Apple store.
That sucks. It was working quite well.
The next most popular adblocker app, which is now the most popular, is Crystal. I read that he is also "conflicted" about the success. Maybe the advertising industry is expressing great dissatisfaction with the iOS ad blockers?
