Probably only "orchestrated" in the sense that it went down almost exactly as planned. The Wagner Group was about to lose some autonomy to the Defense Ministry (I don't know any details) and Prigozhin was not having it, so he did a little Russian Ballet around Moscow in a show of force and then fucked off to Belarus. Putin clearly can't be happy about it and Prigozhin may well suffer a tragic window related accident shortly.
He was clearly unhappy being involved with the Ukraine war and would have much rather spent his days wearing jorts around Africa while doing a little war crimes and sipping mojitos.
