what you are describing doesn’t apply to the above situation. you can’t compare a single use case situation with the whole infrastructure of the government.
usualy when a government infrastructure falls into “foreign hands” you suddenly have a huge problem on your hands that significantly outweighs ANY features which one single individual might feel are more desirable in terms of software efficiency and interoperability.
besides have you tried the latest libreoffice suite ? except the fact that out-of-the-box it doesn’t come with some desirable fonts there are actually very few things it can’t do as well or better than the ms version.
