Switzerland has enacted the "Federal Law on the Use of Electronic Means for the Fulfilment of Governmental Tasks" (EMBAG), establishing a mandatory requirement for open source software within public sector bodies.
The opensource community needs a worldwide Parliamentarian Group for Digital Sustainability (Parldigi) liks Switzerland has. A group that collects money to lobby for opensource wherever and whenever it can. It should further build a global network with projects and governments to allow analysing and proposing solutions to existing governmental IT problems by using opensource.
If we could get something like this going with worldwide engagement, I'm sure Public Money Public Code could become the standard.
The FSF? Is that the one led by the dude who eats his toenails? The one that won't compromise and is opensource or nothing? The one that doesn't have any translations? If so, then that ain't it cuz.
Parldigi was able to compromise to reach a part of their goals and get something this large and important into legislation.
Soweit möglich und sinnvoll sind international etablierte Lizenztexte zu verwenden. Haftungsansprüche von Lizenznehmern sind auszuschliessen, soweit dies rechtlich möglich ist.
As far as possible and expedient, internationally established licenses are to be used.
That sounds like they're not mandating specific licenses, but the GPL is a reasonable choice
The only problem is that there are a number of licenses that purport to be open source, but which don't meet established definitions of the term. The license for Grayjay comes to mind. I'd hope that they blacklist certain licenses like that, rather than enforcing a specific one.
