I question how much Musk is stepping back, but to the extent that he's being forced out and that he's being pushed in front of the bus in the press, nobody should forget who brought him on to the do the damage that he did.
I'm going to go ahead and quote Harry Truman's desk: "The buck stops here!"
Which means the ultimate responsibility for allowing an unelected mentally deranged drug addict to run roughshod over government lies with Donald Trump. Musk deserves rage, of course, but let's not lose sight of this fact either.
