You can kinda witness how science works here, the evolution of the ideas and the hedging of claims.
Did you read through the links in your article? they don't say what you this guys is claiming. The first CDC article says the principle vector of infection is respiratory droplets from carrying the virus, that is a fact, it still is. The key word is principle, mainly etc.. there may be other routes but they are not proven to be the case (as of 2020 when that article was published).
bro, the mRNA vaccine didnt even work when the first tried it, it caused an immune reaction. So if they gave up (they obviously thought it would work) and said its black and white we wouldn't have these now. They figured out that dispersing it in nanadroplets would evade immune degradation, that required research on polymers, colloidal physics and immunology all coming together.
Science is always possibly wrong even when it works, the point of a science is to falsify, you are always trying to prove things wrong. It doesn't mean people were lying but basing things on the best evidence.
The only way this make sense (your assertion) and they purposely lied is if they are trying to control people and just happened to piggy back off the virus or they are egomaniacs who claim untrue things without regard for the consequences.
Or is there another reason they would outright lie?
