I don't think that's a very fair argument. It makes sense to weigh up the legitimate uses of a technology vs. the illegitimate uses and see if the cost is worth the benefit, and if you are unfamiliar with a certain technology then it might not be obvious what the legitimate use cases are. To me it makes sense to take the time and explain the good things you can do with it and why that's worth a few people being able to abuse the technology.
