I understand the sentiment, but as a Dutch person: The only thing I am more worried about than the government moving all our data to US clouds, is the government trying to do anything IT related themselves. They do not have the skill and have proven that over and over again in a long list of bungled projects.
I'd rather have my data end up with Google/Amazon/CIA than it ending up everywhere on the internet due to poorly configured DIY servers (and at twice the cost probably).
If there really is no organizations competent to run government application in the Netherlands, then that is even bigger reason to start doing more of that in the country. I mean, computers are not going away! The competence and infrastructure does not magically appear. It requires consistent investment over time. Not being able to maintain computer based infrastructure is like not being able to maintain water supply of a country. Completely unacceptable.
Heck these days maintaining water supply at city scale is difficult without computers and networking...
Besides: this is not a problem of competence or incompetence of either US companies or Dutch government. It is about the very real threat of US government no longer allowing US companies to provide us with services.
Or stealing and abusing all the data. It's like Russian gas except also the gas pipelines let Putin spy on every government agency and every household.
