my first thought was that it could be disinformationSounds a bit like western wishful thinking to me. I've read several assesments over the past days that go in the opposite direction: that there is great disdain for Putin's handling of the Ukraine invasion, but because he went in too soft with his "special operation" approach and that the generals want all out war.
I can't really imagine Putin being toppled, and even if he is, I don't think he will get replaced with someone we would consider more palatable, quite the opposite possibly.
