You should note the preprint you've quoted refers to a study covering "people aged 13 or more". Therefore, I'm not sure it's relevant to any claim on the risk to "youh children", given the youngest are already teenagers.
“Caution: Preprints are preliminary reports of work that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.”
If your point is that there is a lot of low-quality media out there, then I agree. My sense is that we should increase, not decrease, our skepticism in response.
(apart from implanting 5G of course)
Studies have indicated a positive health benefit for children, so let's get on with it. No politics needed to make that judgement.
