The fact that geoengineering is a concept that exists, and the fact that academics (and the National Academy of the Sciences) have been evaluating whether such concepts are potentially feasible means of influencing climate change (which we otherwise deride when presented as problem), doesn't translate into "contrails are in fact chemicals already being sprayed as part of a huge global conspiracy."
The fact that I'm here means I'm open to it being a conspiracy, but I'm also going to demand a higher degree of logic to avoid being shilled on various distractions.
