Google pulled Adblock Fast from Play Store, an app which enables users of Samsung’s web browser to block ads, according to reports.

Samsung recently announced an official ad blocking API for the browser, which is installed on its smartphones. It was noted that this meant the South Korean company was interfering in Google’s core business of advertising, despite its smartphone success coming off the back of Android.

Adblock Fast, created by Rocketship Apps, was one of the first third-party ad blockers to launch following Samsung’s announcement, racking up around 50,000 downloads and appearing in the top charts in the productivity category.

This is probably why it caught the attention of Google, which told Rocketship in an email that the app “violates section 4.4 of the developer distribution agreement”, according to which apps should not interfere with other installed apps, and was “disabled as a policy strike”.

Google cited the same section when pulling Adblock Plus back in 2013, which only recently came back to the Play Store. Other similar apps are also available.

However, TechCrunch reports that an update to one, Crystal, has recently been rejected. The report suggests that Google will likely continue to support mobile browsers that can block ads within themselves via built-in functionality or extensions, but not if those extensions take the form of separate apps.

In September last year, the release of Apple’s iOS 9 led to a sharp increase in the popularity of ad blocking apps, after support for such products was added.

But the apps were the subject of harsh criticisms from online publishers, who use ads to generate revenue rather than directly charging users to access content.
