If I go to a restaurant with amazing food, and I find that the owner is an asshole, it's completely reasonable to not give them my business anymore. How is it any different with software?
I think it's reasonable, but that doesn't mean it's wise. In software (vs food), the things you choose can impact your bottom line, and if you let your dislike of the authors get in the way of your decisions you could end up hurting yourself. That's not to say you shouldn't weigh the ethical implications of your choices, just that "the creator is a dick" is pretty trivial as far as ethical implications go.
But that's not really relevant here. It's a blogging platform among a sea of blogging platforms.
What's a good example of software made by dicks, such that not using it will kill your business? I'm just interested in one example to think about this.
