Closed standards make software more expensive, and make it harder for new companies to compete against the giants. New, dynamic businesses need cheaper and better software, commercial or free and open source. Such improvements are only possible through open standards.
A true open standard can be used by anyone, at no cost and with no constraints. But some software firms try to call their standards "open" when in fact they are protected by software patents, license fees, and other restrictions.
ESOMA works with other industry groups to ensure that a so-called "open standard" is truly open.
