You do bring up an interesting point, but I think there's a key difference between posting instructions that require unavailable/unproven technologies and technology that is widespread. If I posted plans on how to build a warp drive, it probably won't enable you to build a warp drive, even in the theoretical future when the necessary materials/technologies might exist. There's also a key difference between uncontrolled fission and controlled fission. Both are bad for your health if you are too close, but one of them is immediately bad for your entire neighborhood/district/city.
