There is incentive to play down accidents. No idea what happened here, I actually rather think it recived publicity because falling into a nuclear reactor pool sounds way more dramatic than it is, but ... not my area. Still was happy to get arthurcolle's input.
Misinformation, whether ill-intentioned or not, does real and tangible harm to our society. Misinformation about the supposed dangers of nuclear power, as arthurcolle is spreading, are especially harmful because they form the foundation are the biggest obstacle to safe, clean, cheap, and abundant energy that could radically improve our lives at the systemic level.
I maybe did not read all of it, but which missinformation is he spreading exactly?
(Follow up, why are you in a position to judge that? )
As for missinformation in general, I happened to be born after chernobyl. Where the authorities in eastern germany said, all is fine. But since the people got western television, where they said no, not fine, children may not go outside while the radioactive raincloud is still there, my immediate experience is rather people downplaying the dangers.
Further, your reasoning is biased towards safety (rather than risk), which seems completely sane.
