DeJoy testified to Congress about his sabotage of the US Postal Service, but he didn't take it seriously.

Of course he should be replaced, but the board is controlled by Republicans and they know their mission just as he knows his. He agreed to restore the deactivated sorting machines if the USPS gets a billion dollars in extra funding, but since he's a Republican he would not hesitate to change his mind if that funding is approved. Not that the Republicans in the Senate would permit it.
