The goal is the destruction of NWS as we know it, especially the forecasting parts. By rendering them unable to do their jobs, they can then say, oh, look, this is terrible and "privatize" it. So as long as the current administration is in power, they will do whatever they can to make NWS/NOAA as inefficient as possible.
This was all highlighted in Project 2025 prior to the election.
Here's a summary from before the election:
The administration is using "money-saving" as an excuse. It has very little to do with actual efficiency and much more to do with covering up climate science and also making sure that anything that might have the possibility to make money is in the hands of corporations or private individuals.
