We should ask why we need 5g,not for our Whatsapp and things.For me we need 5g so all third party spyware can send there data on time,so the can send you a commercial of the place you are even before your there.
The known facts are way scarier than the conspiracies. For example one 5g tower can control something like a million devices at once.
The Tyvek suit is "white" making it more comfortable working under the sun. I wore Tyvek suits working in a medical manufacturing lab to protect the product from contaminants I might inadvertently carry in. It is likely that the guy working the cell tower the suit was thrown away because it was probably use also to protect his clothing as those towers can get dirty with bird poop.
