This is true. However, if I owned BK, I'd see this as an amazing business strategy, although a quite unethical one (but as we can see, multi million+ dollar companies aren't the most ethical either way). I mean, now the literal government has an interest for it to stay in business, they may even start to promote the brand.

Except BK is an American company. They wouldn't operate in Russia if they weren't making a profit. So their net effect is to have money flowing out of Russia.
