Yandex is in a very strange position since it has to cooperate with the government and has a strange property structure. If I we're to guess what would happen under a navalny government I guess he would probably limit military spending, increase welfare, and push for policies which favour small and medium sized businesses (especially those in high tech sectors). This would put him directly at odds with the Siloviks of russian society who benefit heavily from the Military-Industrial complex. In order to succeed he would likely have to either moderate himself to gain support from the present oligarchs in russia to kick out the siloviks or he would have to make a clean sweep of the russian socio-economo-political situation to structure society in favour of his view which seems highly unlikely. Russian society essentially resembles Fascist Italy and its corporatism when it comes to how the country operates which took a world war to overthrow and up-end. Either way its not for me to decide, I'm not russian.
