Over 200 Companies Have Withdrawn from Russia – But Some Remain (som.yale.edu)

How many of these companies withdrew BEFORE they were forced by the US government?

How are Russians supposed to tank rouble if they are unable to hand their cash to western services?

That's a long list. I didn't think much at the time when TSMC decided to stop shipments but BlackRock and Bank of China "curtailing Russian access to capital markets"? Even TikTok is suspending operations..
