As for the 5G, a nice summary from a Redditor

Tinfoil hat wearers will wear tin foil hats. This is just the latest of "theories". This one comes from a misconception about how radiation works. Most of the radio spectrum is harmless, which includes visible light, radio waves, microwaves, ect. The only harmful part of the radiation spectrum is the highest energy ionizing radiation, which is stuff like alpha, beta, gamma, ect. particles which have enough energy to knock off electrons from atoms. This can cause DNA damage. 5g is far from ionizing radiation, but when people hear that 5g is "radioactive" they freak out. Like most conspiracy theories, it's a basic misunderstanding (and mistrust when corrected) of the science behind it. It doesn't help that there's """"studies""" floating around that say that 5g causes brain cancer in infants. These aren't real studies but they look real enough to fool some people.

That's the gist. I'm sure there's some other sub categories of conspiracy theorists that think it's a form of population control, or mind control or whatever, but that's a majority of them. They think that it's the bad kind of radiation when it's not.
