Prigozhin was deeply concerned with getting personally marginalized as his private army gets further incorporated into the MoD due to their operational significance. This was evident from his rhetoric around Wagner contract negotiations. So this was his way of saying "I'm powerful, I'm in control, I matter". It was always about him and feeling tossed aside by powerful officials like Shoigu and Gerasimov, who need his army but don't care about Prigozhin. It had nothing to do with policy difference, it was just a pure demonstration of raw power. I would be surprised if Shoigu or Gerasimov get pushed out as a result, I think it is more likely that Prigozhin got guarantees about his own future within the military establishment, something of an "honorary general".
