Not the actual big types, the Gerasimovs and such. They hate Prigozhin and their survival is tied to Putin’s…corruption in modern Russia is a feature, not a bug. Putin purposely selects and promotes people who know they’ll go down without his protection and patronage. Basically his method of rule is to make sure those with the means to take him down don’t have the motive, and those with the motive don’t have the means.
I think he *was* counting on a lot of relatively smaller and ambitious fish - your Lt Cols and such - coming over to his side. Prigozhin has been flogging this “the leadership has betrayed you” line for months now. Perhaps he was counting on riding into Red Square surrounded by cheering regular Army sergeants and Muscovites, and more importantly, streaming that shit live on every media and social media platform out there, imagining that with such a huge display of popular support, Vova would not be able to touch him, even if he didn’t publicly accede to his demands.
