The European Commission has been asking companies that filed complaints against Google for permission to publish some information they previously submitted confidentially. The EU will use the comments as fodder to charge the U.S. Internet-search giant in a five-year-old investigation that has stalled three times and sparked a political firestorm. Shopping, local and travel companies are among those that have been contacted, The Wall Street Journal reports. Aside from search, the EU has been investigating whether Google has been scraping content from rival sites, and unfairly restricting advertisers and software developers who do business with the search giant.
