Well, arguably, other people started this discussion. He blogged about it because people said stuff to him about it and he chose to respond more generally, probably in part to try to reduce the amount of time spent explaining it one on one. Yes, any time you publish anything at all, you risk having someone misuse it.

More importantly, the rest of the world is less likely to hold you responsible. Publishing A and publishing B don't come with equal risks. He is choosing to mitigate risks for reasons that make sense to him in areas that matter to him and explaining it on his blog. You can feel however you feel about that, but he has a right to make those distinctions and choices whether you like it or not.
