I agree with you that the linked article reeks of FUD, but I'd urge you to consider that less caution and oversight wrt to new inventions is not free. Every time we pull a new ball out of the "urn" of possible inventions we're gambling that the pros will outweigh the cons. I can't agree with being too pro-industry and derisive of caution (see: https://nickbostrom.com/papers/vulnerable.pdf).
Thanks for the linked dissertation. I will take some time to read it soon.
I think it makes sense for a reasonable assumption of safety to be demonstrated before deploying new technology that could plausibly be unsafe, and for it to be demonstrated by independently-funded studies.
Given that 67% of independently-funded studies show that the prior, related technologies have adverse health effects, I think it is completely reasonable to hypothesize that 5G could also possibly have negative health effects.
How does anything new get invented in that world?
Also, your linked article is extremely long but ends with this sentence that is just ... well I don't know... ridiculous:
"No scientist can say with certainty how many wireless-technology users are likely to contract cancer, but that is precisely the point: We simply don’t know."
