Red Hat is discontinuing sales and services in Russia and Belarus
So many companies are making these decisions very quickly.  So many that I don't think it has anything to do directly with the war.  They are pulling out because their money people, the only people who really matter in a large corporation, are in a panic.  Nobody knows whether it will even be possible let alone moral to do business in Russian.  How do you get money out when the banks are delisted?  How do you get money into Russia without violating sanctions?  How many of your Russian "business partners" are the subject of sanctions?  Is paying tax in Russia a sanctions violation?  As the Russian government struggles for cash, will any of your corporate assets be seized?  If they are, will insurance cover such seizures?  (No.) The money people also look at the dramatic fall in the value of Russian currency.  Therefor, setting aside all the moral debates about wars and violence, from a purely financial perspective these are all prudent financial decisions.  The PR statements on twitter about supporting Ukraine are just window dressing.
