Microsoft, the ever-present target of scorn from the little guy, has once again been hit with antitrust charges in the EU, according to a report in the Wall Street Journal today. This time it's charges related to the company's refusal to disclose "interoperability information" for a variety of products, including Office, which is keeping competitors from marketing compatible software (we've heard complaints of this type from Open Office users for some time). Additionally -- just as we reported in December -- Norwegian web browser outfit Opera is stepping up to the plate, alleging that Redmond's inclusion of Internet Explorer with its ubiquitous operating system leaves little room for rival companies to enter the game. Considering how Microsoft's last antitrust case went in the EU, this may bode poorly for the giant, though a ruling in favor of reforms could benefit the end user. Stay tuned to this space for more information as we get it.
