The best solution is for governments to write into their purchasing specs that: 1)All software must save to a fully open (i.e. fully documented and unencumbered by licensing requirements) file format by default and 2)Saving to any closed (i.e. not meeting either of the above requirements) format requires going through an "Are You Sure?" mommy popup -- if it's supported at all. This insures access to government data by citizens (no matter what OS or software they use) and by the government in the future (even if they tell their current vendors to get lost).
