Musk's operations likely are using illegal means and are an overextension of power, while legislative and judicial branches, as well as internal executive branch watchdogs, have abdicated their roles in oversight and control. This is effectively an overthrow.
When I read your comment I am sympathetic to your characterization that its illegal. I expect it will be litigated.
But then you conflate illegal with "an overthrow" (of what?) to show its a "coup". This is incredibly hand-wavy and makes the "coup" language look like hyperbole.
Trump is essentially ruling by decree and taking actions far outside his authority. If successful, this will de facto strip Congress of much of its power and transfer it to the President. If you want to see what the outcome of that looks like, read about events in Germany in January-March 1933.
