A petition worth signing. It points out to two major issues where the EU Parliament using Microsoft software conflicts with the Treaty of the European Union: forcing people into using Microsoft software (e.g. Windows Media Player) to access content that is supposedly accessible to the widest audience, and not enabling open competition. Concise and to the point. If not open source software, the EU must at the very least mandate and enforce the use of open standards. Check out the complete text of the petition.
