An anonymous reader writes: Following a four-month trial, a German court in Hamburg has ruled that the practice of blocking advertising is perfectly legitimate. Germany-based Eyeo, the company that owns Adblock Plus, has won a case against German publishers Zeit Online and Handelsblatt. These companies operate Zeit.de, Handelsblatt.com, and Wiwo.de. Their lawsuit, filed on December 3, charged that Adblock Plus should not be allowed to block ads on their websites. While the decision is undoubtedly a big win for users today, it could also set a precedent for future lawsuits against Adblock Plus and any other tool that offers similar functions. The German court has essentially declared that users are legally allowed to control what happens on their screens and on their computers while they browse the Web.
