Google's tough stance on dedicated Android ad blockers might be softening a bit. The company has reversed its decision to yank Adblock Fast from the Play Store following an appeal from the app's developer, Rocketship. Google hasn't officially said what prompted the change of heart (we'll let you know if it has a comment), but TechCrunch understands that Google had originally wanted to limit ad blocking to browsers where it's an option -- any stand-alone apps were against the rules for interfering with other software. Our understanding is that Google is now concerned solely with banning those apps that interfere without permission. Given that Rocketship was working with Samsung, that shouldn't be a problem.
