By continuing to work their jobs and pay their taxes those those asset managers and analysists are contributing thousands of dollars a year towards the Russian state, and thus to their attempt at genociding Ukraine. An estimated 10% or more of the entire Russian GDP is being spent on the invasion. You simply can't escape supporting it if you continue to stay in Russia and work. And with those kinds of careers, they probably do have a real choice and could leave Russia like so many others have.

Unless your contacts are doing something useful to stop the war, like sabotage or espionage, they should be thought of as criminals. And they – and the Russian economy in general – should be considered valid military targets. It would be completely ok for Ukraine to send a few drones to their offices to fuck up the financial side of the Russian economy.

War is shit. But sometimes you are forced to take a side, and forced to make hard choices. Don't chose evil.
