At least based on the picture, the flag appears to be flown flipped from the end that isn’t normally on the flag-pole side. So like seems like a point of using it as an insult, since everyone still likes to act like Russia is still the USSR. So I am guessing it is just reactionaries being reactionaries and not using the Russian Federation flag since it is less “scary” or something compared to the USSR (from the perspective of anti-Soviet right-wingers).
Though at the same time, you could argue that it is flipped because they just didn’t know how to fly it properly. Though I think you’re right, this is probably intended as some kind of anti-communist thing.
