They probably paid money to get them/build them. Probably near impossible to just "sell and cash out".

But that's on them and any corporation that invested in that cesspool. Stupid risks, worse consequences.

It matters because the factories and more specifically, the workers who fill them are the ones creating value. Had they pulled out sooner, the result likely would have been the same, the state taking over management.

While I don't particularly care about private property being "repossessed" by the state, especially in an oligarchal capitalist state like Russia where it's not likely to have any large material benefit for the working class, its just funny that liberals throw stuff like this around without any analysis of the situation.
