Germany 's supreme court , the Bundesgerichsthof , has ruled that Adblock Plus , developed by Eyeo , does not interfere with press freedom nor " constitute an aggressive commercial act " . So far, the only time the court has found against Eyeo was when a Cologne court ruled in 2016 that the company could not charge publishing giant Axel Springer for inclusion on its whitelist. Publisher Axel Springer , which filed the lawsuit , argued AdBlock Plus violated German copyright laws and threatened the " quality and variety of information services " . Laura Dornheim , Eyeo 's head of communications , said the publisher had " plenty of ways " to defend against ad blocking and praised its digital media department 's " double - digit revenue growth " . Axel Springer will appeal to Germany 's Federal Constitutional Court .
