That's not contradicting anything I said, on the contrary it's contradicting your assertion that those people would be funding the war. Their wealth is largely unaffected, still making profits (even if a bit lower) because they're still fulfilling their purpose as loyal viceroys.

Like, usually they could e.g. produce ballistic vests out of cardboard, bill the army full price for the things, and pocket the difference. That doesn't fly any more but that doesn't mean that suddenly their businesses are unprofitable.

Among kremlinologists there's generally an acknowledgement that the viceroys aren't exactly thrilled about the war because it's cutting into their profits and they're not seeing any point in it, OTOH they're also not willing to bite the hand that feeds them. Few have armies large enough to march on Moscow, none have armies large enough to face down the actual one, and none of them wants to end like Prigozhin. They also don't like not being able to travel to Monaco. They're assholes captured between a rock and a hard place. Normal Russian circumstances, one might say.
