When I was a student pilot, I filed a flight plan for my night cross-country to an airport S. of Phoenix. When I got in the air and went to open the flight plan with FSS, they told me, "That airport is closed at night. Didn't the briefer tell you that?".
I wanted to say, "Do you think I would be flying there in the dark of night if he had?", but I kept it professional and filed for a different airport.
Most of these FAA guys and gals mean well, but they are still bureaucrats and are protected from any consequences when they screw up.
But when a pilot follows their instructions and flies into the wrong airspace, it's the pilots fault, legally speaking.
