The European Union’s competition commissioner, Neelie Kroes, delivered an unusually blunt rebuke to Microsoft on Tuesday by recommending that businesses and governments use software based on open standards.
Ms. Kroes has fought bitterly with Microsoft over the last four years, accusing the company of defying her orders and fining it nearly 1.7 billion euros, or $2.7 billion, on the grounds of violating European competition rules. But her comments were the strongest recommendation yet by Ms. Kroes to jettison Microsoft products, which are based on proprietary standards, and to use rival operating systems to run computers.
“I know a smart business decision when I see one — choosing open standards is a very smart business decision indeed,” Ms. Kroes told a conference in Brussels. “No citizen or company should be forced or encouraged to choose a closed technology over an open one.”
