Germany could ban ad blockers on the Internet, in a potentially historic shift in the way users browse online. Although no final decision has yet been made, the alert has been raised by Mozilla, which fears that the country may follow the example of China, where these tools are already prohibited.
At the heart of the controversy is a long legal battle between the publisher Axel Springer, owner of some of Germany’s biggest newspapers, and the company Eyeo, creator of the popular Adblock Plus. The publisher sees ad blockers as a direct threat to its advertising revenue and has turned to the courts with various legal arguments, without so far securing a favourable verdict.
Initially, Axel Springer alleged anti-competitive practices, but it changed strategy, now invoking an alleged copyright violation. In 2022, the Hamburg Court of Appeal rejected that line of argument, holding that Adblock Plus merely allows users to choose how they wish to view web content.
However, the Federal Court of Justice (BGH), Germany’s highest court, challenged that decision, finding that the ruling lacked sufficient reasoning. The BGH left open the possibility that the code generated by the browser when rendering a web page is, in fact, protected by copyright – which could make the action of ad blockers a legal infringement.
As a result, the case returns to the Hamburg court, now with a new legal framework to consider. The decision does not yet represent a victory for Axel Springer, but it marks a reopening of the debate that could culminate in a formal ban on these extensions.
Mozilla, the developer of the Firefox browser, strongly criticises this legal turnaround, describing it as “flawed logic” that threatens online freedom. It stresses that users trust their browsers and their extensions not only to remove intrusive advertising content, but also to protect their privacy.
And, indeed, the function of ad blockers goes well beyond the simple removal of banners or promotional videos: these tools also block tracking scripts, invisible to the user but operating behind the scenes to collect personal information – such as browsing history, location, spending habits and even sensitive data. The removal of these trackers represents an additional layer of defence against commercial surveillance and algorithmic profiling.
Although the outcome is far from being reached, the precedent now set could have cross-border ramifications, influencing Internet regulation across Europe. The case, which may still drag on for several years and through several courts, marks a turning point in the balance between the rights of content creators and the digital freedom of users.
