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.
It is not like Putin he is winning,his first strategical objectives have been not met from the army of Russia,they are suffering heavy losses and will continue to suffer even more,Ukraine is firmly convinced to fight for their freedom and they will do so as long as they have power to do so.They have made considerable advances in Kherson and Kharkiv region,although they are losing in Donbas right now the fact that they are liberating other areas shows that the war is far from over.The only ones paying the price of the sanctions so far are the Russian civilians who strangely enough do not care that they are being isolated from the whole world.
