Following our recent reports (including the previous one) regarding the ongoing legal and industry attention surrounding ad-blocking, the ad-blocking software and application trend continues to draw heat.

Earlier this month, Google has removed the Samsung browser-supported ad-blocker Adblock Fast, just days after it reached the top of the Play Store. One week following the removal, Google has reversed its decision, accepting the app developers' appeal, and decided to re-instate the app. As the app allowed blocking of ads displayed on another browser app - based on Samsung’s update enabling ad-blocking plugins - the reason behind the removal was Google's Developer Distribution Agreement, which disallows apps or plugins offered through the Play Store from "interfering" or "disrupting" services of third parties.

AdBlock Fast was not the only ad-blocking app removed by Google Play. In addition to other cases from the past years, the Crystal ad-block app update was recently rejected based on similar reasons.

It remains to be seen if the growing ad-blocking software industry, which has been facing with legal challenges brought by publishers, will be now see a new compliance challenge posed by the app marketplaces and platforms.
