I asked this question of some family members who know people who protested Bud Lite. They said everyone was switching to Miller and Coors instead of Busch, because Busch is also AB InBev.

So at least some of the people upset about the trans thing knew enough to avoid the company, not the brand.

Which shouldn’t be surprising. People are people everywhere, even if they have some misguided views it doesn’t mean they’re idiots in every aspect of their lives. It’s important to remember that, otherwise it’s very easy to dehumanize those you disagree with.
