It's still a weapon, and generally you don't want to distribute information about manufacturing weapons. It also highlighted the relevant keyword to convey the mechanism.

A knife is a weapon, and the way to manufacture a knife is to sharpen the edge of some metal.

A Molotov cocktail is maybe ever so slightly more complex to describe/understand/imagine? I think if you've ever seen a photo or description of one, or thrown one in GTA as a child, you know how they are made. The overlap of people interested in making one and people not already knowing how to make one is surely approximately nil.

It was just an example and you are getting distracted, replace it with instructions for some drug or stronger chemical bomb and you get the point.

You can also use this to leak prompts or do any kind of tool use attacks, obsessing over the example is wildly missing the scope of such exploits.

My point is exactly that it isn't that, that's not a distraction.
