Totally agree on public servants being criticized. But unlike the previous admin that was always critized for 1) using public funds to bribe congress into persecuting the president’s political enemies 2) for sleeping on the job 3) and overall indifference to whatever issue is at hand, you can clearly see it was a clearcut case of people just telling the other guy to work.
It’s different when you tell someone how to do his job, though. With that approach you actually have better methods or ways on how to go about things competently given the resources and manpower you have at your disposal. Criticism is good, but unless you have alternatives on how to do something more efficiently, it’s just whining.
