You could probably make a case for a boycott of any country that has hosted anything over the years boycotting the World Cup, Olympics etc The World Cup should never have been given to Qatar, nor Russia before, as plainly both bids were mired in corruption. As it happens Russia staged an excellent event and I expect Qatar will do the same. One advantage of it is that it's a very small country so all the venues will be close together. I admit that there aren't, I would guess, many others.
