One of the features that emerges early in dementia is a loss of inhibition. About 6 months before my dad lost all semblance of the ability to live independently, he would just…say things. Absolutely no filter, and often grossly inappropriate and rude. Now add that on top of a baseline of awfulness…

What is happening at Goddard is absolutely devastating. We are losing history. We are losing an incredible amount of human talent, skill, and knowledge. Rebuilding it will be impossible same for same. Industry can not absorb the people or the equipment. This is undoing space science in the US.
Goddard spacecraft engineer: "I think it just kind of speaks to the atmosphere of the agency and the nation, where people are like, 'Well, laws don't matter for the people at the top anymore.'"
NASA is sinking its flagship science center during the government shutdown — and may be breaking the law in the process, critics say
"There is just a general acknowledgement that a lot of what is happening is illegal…"

This triggered a core memory of a road trip with my very young kids, where we would go around and add a sentence to a story in turn. I started with “once upon a time there was a little girl.” Which was serenely followed by a lispy little kid voice adding on their part: “And she was eaten by wolves.”

I'd like to commend the lawyers who wrote this complaint on behalf of the professors and employees of the University of California against the Trump administration.
It's a sober legal document with strong claims, but also, this is a fight for public opinion, and this reads like the writers know it.
