Petition to UK govt for open source software

I've just found out about a petition to the PM about making public money funded software development to be done using a Free license. I think this is a great idea, BUT I have a MAJOR problem with the language of the petition. The petition is titled "Open-IT-projects" and Open and Free aren't the same. I also don't like that the choice of license is to be dictated by the FSF (Free Software Foundation) rather than OSI (Open Source Initiative), the former could imply GPL, LGPL only but the later would allow other licenses such as CDDL. I'm not sure if I'll sign this petition or not as it stands.
