Cato - one of the few actually principled right-leaning think tanks have written extensively about this (and other instances of Trump administration contempt). It’s just as bad as you’ve described and infuriating for anyone who actually values the rule of law.
Courts rarely punish agencies for contempt and trust erodes, but shame no longer works and two cases aren’t proof of a systemic collapse.
Those ‘two cases’ were from the first months of this term - needless to say there have been many further cases since then.

Fair, but linking more cases doesn’t automatically prove systemic collapse either.
