Same with Holland. The tax office is moving away from their own office package onto m365 right now. They apparently had an alternative all this time, which I find very surprising (the media didn't really elaborate on this).
But Holland, Ireland, UK are the most neoliberal countries in Europe, they worship America and believe that the market solves everything. The rest of europe doesn't share that sentiment to the same extent.
Hell yes I hear you on that. I've been sideways involved with some of their projects too. It's always a minefield because they don't know what they want, what they do think they want makes no sense and they don't care about what's technically possible or is streamlined, maintainable and affordable (us engineers try to find a solution that is also robust and straightforward, not just to tick a maze of boxes).
Governments tend to write the legislation of everything under their purview and they don't really have to deal with forces of nature so they think they can just decree water to not be wet and that's sorted then. So their resulting solutions tend to be pretty awful. Oh and the decision makers tend to be there because they're great at spouting hot air, not because they have a clue what they're doing. Not fun projects to work on.
Most corporates are much more flexible. They come to you with a vision and you discuss how to best make this happen. And an 'Actually, it would be a lot simpler if you do ...' is very appreciated.
