That doesn't mean this is the same situation. In examples you are likely thinking of, this is happening because of the immediate need for parts or as cost savings, etc. Russia is doing it because they are blocked from primary and secondary markets. For many of their aircraft in the country there are no replacement parts coming except what falls off of the truck in China and gets passed along. So their supply chain is slowly approaching zero until their aircraft have to simply be grounded (or they quit invading neighboring countries and the embargoes are lifted.)
