To be really honest, I share a similar stance to you overall but I would still admit that there is some partial truth to it
I would like to expand this not only to foreign state actors that people mention but also companies inside which are actively trying to do nefarious stuff
As an example, Tobacco industry knew that the damages were there but they still tried to spur up medical confusion around it all so that people would still think that medical discussion is going on when it was 100% clear that tobacco harms. Who knows how many people died
The man who discovered that washing hands saved lives was so ridiculed and I think met with hostility because doctors couldn't comprehend the idea that it was they would could spread diseases. This is decades before germ theory was invented
His name is Ignaz Semmelweis and the world was unjust to him. Doctors ridiculed and threatend him and he was labelled obsessive and doctors called it mere coincidence. His career crumbled as he was forced out of vienna/his hospital and his mental health deteriorated as his warnings were ignored
in 1865 Semmelwise was commited to an asylum where he died just two weeks later at age 47
Only after pasteur developed germ theory and lester pioneered antisceptic surgery, semmelwise was finally vindicated.
This simple practise of handwashing is now considered the most basic medical standard worldwide saving countless millions of lives in the process.
(I had to write it by hand here basically transcribing this really amazing video that I watched about such a topic, I would highly suggest watching it)

Semmelwise's stories can brings chills to spine.
