uBlock Origin gives up: Facebook's ads are impossible to block The world's best-known ad-blocking application, uBlock Origin, has had to conclude that the software's development team has met a tougher opponent than itself.
According to the developers, they have decided to definitively give up even trying to block Facebook's ads.

The reason behind the decision is that Facebook constantly changes the technology of its ads when some larger ad-blocking software learns to identify and block them.

Facebook, owned by Meta, is able to do this trickery because the ads displayed in the company's services load directly from Facebook's own servers. The lion's share of regular online services use external parties to display ads, but Meta itself is one of the world's largest ad distributors, so the company can freely tinker with its ad technology.

The developers announced their decision on Reddit, describing Facebook's practices as "disgusting".



The development team has not completely thrown in the towel regarding Facebook's ads either; instead, the team encourages volunteers who are interested in the challenge to participate in the development of uBlock Origin. However, the current developers will no longer spend their time on a cat-and-mouse game with Facebook.
