Well said, I never supported the boycott of the Russian gambling platforms just like many Russians never supported the agenda of Putin to attack the Ukrainians. I think for their boycotting of the gambling platforms owns by Russian citicens is to compel Putin to stop his political agenda. I don't think this boycotting will have much effects on Putin's agenda.
The opinion is very right that many Russians don't want war to happen, but what happens in war is the will of the government and has nothing to do with civilians. So it's an unfair decision if we condemn everything about Russia including the gambling platform because the platform owner has absolutely nothing to do with war.
Casinos that are registered in Russia have to pay taxes on their earnings. Tax money goes into the Russian budget, and then this money supports the war, so it is somehow related to that war. The less money Russian casinos make, the less money there will be to prolong this war. The sooner it ends, the better, so boycotting Russian casinos is a good thing.
