Unfortunately, that's not true either.
There's this "EMF radiation is dangerous" dude, Martin L. Pall, who to the best of my knowledge is to health and WiFi (and 5G and 4G and 3G) as Andrew Wakefield is to vaccines and autism.
I've had the misfortune of having this article https://www.sciencedirect.com/science/article/pii/S0013935118300355#t0015 waved in my face: “Wi-Fi is an important threat to human health”
I won't reproduce any of the "research" here – suffice it to say that they claim there are biochemical/bioelectrical pathways that are being messed with.
There *are* the conspiracy nuts who think the whole thing is a giant cover-up/conspiracy – those folks are well into tin-foil hat territory and are seriously out to lunch, as in they have (and I mean this in a very literal sense) very little grasp on reality. There's another segment who are scientifically illiterate but realise that they have to make scientifically grounded claims and for these folks quacks like Pall (who push junk meta-analysis fear-mongering) are just the ticket.
And if that wasn't bad enough these two groups are not even the same crowd as the "don't-tread-on-me, it's just the flu bro" folks.
Not one, not two, but at least three distinct Sars-cov-2/Covid-19 rejectionists !
I've lost friends over this so I know what I'm talking about :/
