Not just that, but a lot of Russian people do not support this war.  They are facing the consequences of actions they don't want to be happening.  Their stock market is wrecked, their currency is fading fast...  It isn't their fault.  Many of them are probably seeing Bitcoin as a lifeline to protect their life savings.  It would be wrong to lock these people out of the system just because of a government disagreement.  There is KYC in place to make sure that Putin isn't using Binance to avoid sanctions.  I think a lot of people just want to cause Russia the most harm possible, without thinking about the fact that there are real people suffering on both sides of this war, and I'm sure a vast majority of them wish it had never happened.
