I am living in Spain, and from my point of view, Netherlands is one of the ones doing the most for FOSS in Europe today! It sees much faster real-world adoption of FOSS in ministries and municipalities than other countries, the government seems eager to fund FOSS (again, compared to other countries) and generally be welcoming to the ecosystem. Browsing around, there seems to be lots of FOSS projects funded by money coming from the Dutch state.
Kind of interesting how the perspective is so different from the inside! Maybe it's the typical "the grass is always greener..."?
This map shows that the Dutch municipalities are nearly all in the Microsoft cloud.
