"an open conversation about knowledge that can easily kill people"
This phrase and the article contain the same fallacy ( ("disclosing 0days when they can kill people"). I may be accused of semantic quibbling here, but I think it is important to state the issues clearly and accurately.
Information cannot kill anyone, nor exert any effects at all, ever. It is not causal. Actions using the information may be enabled by knowledge of the information, but they are human choices and not automatic.
This is not merely a matter of careless expression that does not affect the argument. In fact the fallacy is not only, or not exactly supposing that knowledge is causal, but rather in eliding the whole articulation of what happens between the revealing or acquisition of knowledge and the action that may or may not use it in some way.
The situation has a common element with the gun control issue: if someone has a gun, violence is easier, and this may be considered bad, but it does not excuse conflating the shooter's action with someone else's conduct of merely allowing that person to have a gun. It does not shift any responsibility from a competent adult actor to someone who merely allows a gun to be available.
Note also that the gun-possessor, or the person newly armed with knowledge, need not act on it at all, and those who confuse things by missing these distinctions manage to avoid the fallacy in those cases.
