I'm sure that the Brewers would prefer to have a stadium full of Brewers fans. But having a stadium full is still pretty great. I really don't think it's a big deal, or embarrassing, or outrageous that Cubs fans come to Milwaukee to watch their team. Yes, there are some jerks in the crowd, but that's up to Security and the Sherriff's team to handle. When the Cubs stink again, those fans will fade away.
