Yes.
I don't buy Nike products because I don't like their politics. New Balance or Reebok or WhoEverBrand is just as good and just as accessible. So since there is an easy alternative, I'll go with the alternate.
I do try to separate the "talent" from the "personal things". Robert DeNiro has done some great acting (and some not so great too). I don't like his political views, but I'll not refuse to watch a good movie in which he is featured because I'm watching the fictional character that he is playing.
On the subject of actors, I don't know why they think their freaking opinion is any more important or better than my opinion. Unless they have some education or related experience that qualifies them as an "expert", why would anyone give a shit what they think about [ pick your subject ].
