The loss is tragic but I’m sorry GPS jamming was not a factor here. There was a NOTAM indicating it’s going on, the pilots should have been aware and it appears when they reached out with a request the jamming was stopped.

It was a visual approach at a moonless night at an airport in high terrain, this was pilot error unfortunately.

I'll bet that the NTSB will list GPS jamming as a contributing factor. I agree with you that it's not the primary cause of the accident.
