Other - Yes, but not always.
It depends on the author and the degree of his or her transgression, vs the coolness of the product. I almost never pay attention to the real-life antics of authors. For the most part, I don't want to know, because while I know that authors are people like any other I also don't want to find out something that ruins the experience for me.
Victor Salva, for instance, is a convicted sex offender. Yet I've enjoyed the three movies of his I've seen very much indeed. Orson Scott Card's personal opinions make me very angry but his Alvin Maker books are some of the best-written fiction of that genre I've ever read. Just as an example, Salva has paid for his crime while Card continues to make his assertations. It's a difficult choice to support him financially while disagreeing with his personal opinions; since finding out about his predilictions, I've not purchased anything of his, but then again he hasn't produced anything I've particularly been interested in so I would not have made those purchases in any case. If he did, then I'd find out what choice I was willing to make.
A personal opinion can disuade me from making sales but it depends on what that personal opinion is and if it touches any of my hot buttons, as can behavior that is not becoming a professional. Personal attacks, airing dirty laundry in public, and other things can cause me to reconsider purchasing something by a particular author or company. Then again, I hardly ever even look at the credits for a product at all. There are only a handful of names I'll react positively to, and give additional consideration to purchasing a product just because X was involved in it. Monte Cook, Mike Mearls, Skip Williams and three or four others all come to mind in that regard.
