This is just textbook APA stuff. There is no such thing as a legal blanket ban. The executive does not have the authority to do any of this. And I will bet my money that MS has been following the law. Hopium and copium are free though, so I can't stop you from smoking it. The most likely outcome here is again a settlement after the midterms and some money thrown at Trump or Vance.
I believe you need to get a better textbook. The debarment program started in 2007 [1]
