Doubt it. He probably just thought the app wasn't going to be so popular. He's selling a lot of copies and he just doesn't feel comfortable with it. Hats off to Marco for putting his ethics first, not the money.

I said this yesterday and I'm going to repeat myself in this thread: adblocking is not going to "fix" the web as people are saying, for the simple reason ad blockers block all ads, not only annoying ones. The big publishers probably are not going to even notice it, because they have other ways of making money, but the small blogger will have a hard time when the ads on his blog get blocked, probably the only source of income for his site.

And we're forgetting people that can't afford anything besides some little AdSense ad to advertise their business. How are they going to reach people if all their ads get blocked?
