I assumed it was a staged thing from the beginning. Significant for some hidden purpose, not what it seemed.
I think Prigozhin had a larger purpose, and still has a larger propose. I think his being in exile is also a thing which is staged.
I've guessed what it is and have posted about that. I'm waiting to see how well I guessed his underlying purpose based on other factors I also see aligned with it.
I see the beginning of an end of this war.
