you will have to submit expense and planning reports to the eu commission to get those sweet grants, but they will require you to use a centralized exchange email account they manage, then send in a Microsoft office file format, then use an authentication app that only works on google-android or ios...
it doesn't matter that one single country wants to break free from the domination that is rooted in the Belgian burocracia. and I'm not guessing, in talking from historic precedent. Spain, Italy, France, Germany... they all tried before and failed.
For the freedom it would be better to break from the Google for example. However I really cheer them for it, it will fail, because Linux and open office are not replacements for normal office work.
