Marco Arment, on Wednesday:

Today, I’m launching my own iOS 9 content blocker, called Peace, to bring peace, quiet, privacy, and — as a nice side benefit — ludicrous speed to iOS web browsing.

There are a lot of content blockers being released today, but Peace strikes the best balance I’ve seen between effectiveness, compatibility, simplicity, and speed, powered by what I’ve found to be the best database in the business after months of testing.

Marco Arment, on Friday:

I’ve pulled Peace from the App Store. I’m sorry to all of my fans and customers who bought this on my name, expecting it to be supported for longer than two days. It’ll keep working for a long time if you already have it, but with no updates.

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. If Overcast even broke the top 100, I’d be over the moon.

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.

The App business is really hard. It’s easy for people on the outside to judge Marco for his decision, and criticize the week he’s just had. Good on him for sticking to his morals and doing what he feels is right.

For what it’s worth, the app is great and I’ll be keeping it installed.
