A few points:
No fly zones aren't a thing. It's what you call your wars for domestic consumption if wars are unpopular, but it's not going to trick the party that gets its air defense destroyed.
I wouldn't be too sure about the Russian army doing terrible. The regulars on both sides seem to have learned the lesson of artiCalcDroid and left their phones at home. So most of the video content comes from Ukrainian irregulars and civilians, then gets signal boosted. There was a similar effect in the recent war in Armenia where the more sympathetic side also seemed to do a lot better than they did. We'll see in a few days.
Finally, not sure what Russian info ops are supposed to have contributed. Sure, I didn't believe the Americans about the Russian invasion, but that's hardly an effect of Russian disinfo, unless the Russians tricked US intelligence into claiming a Cuban beam weapon that causes hangovers and sounds like cicadas was hunting their agents across the globe. Zelensky certainly didn't seem to believe them.
