Probably it can somehow affect the peace between the two countries, not directly though. Think of it, if Russian online casino has been successfully boycotted by the gambling community, the tax/revenue that the government are getting from these casinos (Players/owners) will be lessen. Funds less, less armory, etc. That is if Russian government is getting something from Russian casino owners. Or if they are being taxed. If no, probably it won't have any effect on the peace between Ukraine and Russia.
