The WHO and WEF are aware of bioweapons research and are planning how to deal with the fallout if another one of them leaks. Some of them are very afraid, afraid enough to want total worldwide sovereignty, which makes me wonder if they know something I don't... or maybe they just lust after power. But I'm not even a little bit convinced that they intend to develop/release something. That is a step too far for me.

Do people lust for power? Yes. Is incompetence widespread? Yes. Do people cover up things that make them look bad? Yes. Conspiracy theories that posit such things are easy to consider plausable. But conspiracy theories that posit the intent of a global organisation to kill massive numbers of people... I don't think there are enough humans that desire that outcome for such a theory to be rated "plausable". Not in my assessment.
