The question is: what CAN they do? How would they triage transactions? Everything Russian? That's laughable. There are many Russians who oppose Putin's war.

Furthermore AFAIK it's pretty easy to simply use another exchange so how would it work? Even besides ideological ideas as described in the article. How would the technically decide what and what not to allow?

Classical finance has similar problems I guess. But not the additional technical layer since they use highly centralized systems.
