This is a moronic take, the kind of thing only some western Gen Z cancel culture warrior with no life experience would believe in. Radiohead understand that large numbers of their fans live in countries with questionable or outright authoritarian governments (they are massive in South America, for example). It would be very problematic if they started picking and choosing which of their fans was deserving of a live concert based on where they live or what kind of policies their government has been pursuing. Their music is something that unites people from all over the world and continuing to share it with everyone is the best thing they can do in this situation.
