It’s one thing to say “I make hammers, and can’t be responsible for the fact that some people use them to break people’s kneecaps.”
It’s another thing to hand out free hammers to the kneecap-breakers, or pay them to use your hammers instead of someone else’s, or hire them as spokespeople, or use their testimonials to promote your business. “So-and-So’s hammer is the best for breaking kneecaps! And you can quote me on that!”
Under those circumstances, claiming to be opposed to kneecap-breaking wears a bit thin.
