They are forced to do that,it is not their choice,it was dictated as a response after the move from Russian president Putin.Now also the citizens of a country who goes to a completely unjustified war will have to suffer the consequences in order to stand up and get back their freedom,they now cannot pay anything in dollars unless they have an account with the banks that are out yet of the SWIFT ban,for example they cannot buy goods from ebay,no jobs will be offered to them from many European companies from what I am seeing on Linkedin and if they don't stand up now for freedom (economic freedom I mean) then they will become as one Russian citizen was quoted saying unfortunately another N.Korea completely isolated.
This example should serve well to common Russian citizens to not elect ever again a lunatic person as a president anymore.
