Well if the the sanctions which have been imposed by the US and their allies have not been enough to stop Putin from invading Ukraine it was unlikely a small boycott was going to have too much of an impact, but despite all of this if people want to vote with their wallet and not support any casino which has any kind of relationship with Russia then they are on their right to do so.
Putin knows that he has power and without oil and gas world would collapse. So he is not listening to anyone. Even the sanctions had no effects on Russia and seem like they are going to invade most past of Ukraine. Sad for Ukraine but Putin should have mercy on people and stop the war.
Quite often it looks like the war have come to an end, but it continues. Russia have missed many important sporting events. Ukraine on the other side came close to the qualifier and lost to Wales. If not Ukraine could've got into this year's FIFA World Cup 2022. Boycott isn't necessary and every sportsman is talking about peace and Russia doesn't have plans of hearing it.
