Does anyone even question, how much resources go into this ? Man hours, equipment time, fuel costs, training, etc. It's in the tens of billions of $, to spray aerosols over the people.
And if it weren't targeted at the people, and were a legitimate atmospheric screening project, it would be being done over the oceans, away from the people, and launched from shore or carrier craft.
But it's being done over populated areas.
Take that for what you will, and adjust your idea of who your friends are by it.
