I guess what he meant was that big retailers colluded to increase prices simultaneously together in lock-step for no reason other than greed and profiteering, and simply blamed it on the Russo-Ukrainian war as being the reason for prices exploding.
Not that I doubt that big corporations would use the Russia excuse whenever/wherever they can - I mean, who wouldn't - but I'd just like to see the details that tie the inflation to support of Russia a bit more clearly laid out.
