Because there's a huge amount of evidence[0] that these harms are fictional, created and promoted by a mix of new age anti-tech people, snake oil salespeople touting literal tinfoil hats, and scammers looking to make a quick buck.
The whole thing is nonsense, and there is an abundance of evidence of that. There is literally no evidence of these supposed widespread harms that are somehow both an existential threat and not measurable in thousands of studies and hundreds of meta-analyses.
So, yeah, asking for info here is like saying "gosh, maybe smoking really doesn't have any health impacts, I'd love to see some studies on it."
