That doesn’t necessarily mean there’s no need to be concerned with potential impact of policy and priority changes from the administration, but it does temper the threat model because the government employees you’re considering trusting have given oaths of office to protect and defend the Constitution.
US national lab scientists are not even civil servants. The labs themselves are run by a corporation under contract to the DOE and the scientists work for that corp. The managing corporation changes from time to time and the scientists transparently start working for whatever assumes the replacement. The land, the hardware, the buildings and any physical products are owned by the US gov't. To a very large extent, the intellectual output is set free to the world in the form of papers, presentations and to some small extent (eg compared to CERN) in the form of software.
As an added complication, some of the DOE labs do have civil servant scientists, for example National Energy Technology Lab and National Renewable Energy Lab are like 50/50 civil servants and contractors. And most of the funding arm of DOE are career civil servants. LANL, Sandia, Livermore, Argonne are all staffed by contractors
I agree with this.
I'm a civil servant and I know (personally; my work is nowhere near the labs) a number of people who work or have worked in that weird contracting DOE/DOD structure that includes the labs.
The difference I've seen is far more from the nature of work rather than the employment details.
