In 2010, talking about issues like privacy and copyright, she complained about Google's instinct for "pressing ahead" and its "megalomania". That same year, she asked Apple Inc. to tell state data protection officials about the kind of data the company was gathering on individual iPhone users in Germany. In a case Leutheusser herself brought to the Federal Constitutional Court of Germany, the judges eventually rejected a core piece of security legislation that requires data on telephone calls and e-mail traffic to be stored for up to six months for possible use by law enforcement and intelligence agencies. As part of the draft of a law governing workplace privacy, she proposed placing restrictions on employers who want to use Facebook profiles when recruiting. She also expressed her support for legislation that would punish officials who purchase illegally obtained data of German tax evaders in Switzerland.
