If it were me I'd be sacking people until they started getting a mean adjustment somewhere around 0. I doubt that is what Trump is doing, but the managers left themselves vulnerable to technical criticism.

Why sack them? It's not like they refused to mean adjust or failed to do so. The numbers came out, and before anybody has even had a chance to question them. Before any coherent criticism as had time to root, the person responsible is fired.
Firing people is not how you get more accurate numbers. It's how you get yes-men.
When reality and truth do not matter, why would they want accurate numbers? They do not need the country to flourish, they just need their personal wealth to grow and the rest of the population to remain compliant. From that point of view, shooting the messenger before the message gets out of control makes perfect sense. It is working well enough for many autocratic regimes around the world.
