It's not about the cost, it's about ideology. Same reason they've paid nearly $2 billion in taxpayer funds to energy developers to abandon offshore wind farm projects. The point isn't to save money, it's to stop green energy projects, which is an ideological goal. If their decisions don't make sense to you it's because you're not viewing them through their ideological lens.
It's not an ideological goal, it's a profit goal. Ideology is just part of the propaganda engine. Isn't it funny how conservatism always seems to benefit big business? Have you ever noticed how quiet conservative politicians get when some supposedly conservative ideology ends up being bad for big business?
The way I thought it worked was that congress would set a budget and scientists would decide how to spend it.
Perhaps naively I thought these scientists would want to do science and would be unwilling to steer funds away from whichever projects they liked in order to fund the removal of some sensors.
I guess maybe the scientists who make these decisions are also partisan and happy to do as the administration asks.
