I had to create an account just to post this, people like the guy that made the video in the OP are genuine scam artists and should be held accountable. The sad part is many people believe videos like this without giving it a second thought, get scammed into buying junk like rf protection gear etc, then tell their equally gullible friends who go on to make the same mistake. Lather, rinse, repeat.
Whats hilarious is the number he quotes from his own World Healthy Organisation reference link is totally wrong. He says 100mW/m² is a safety limit, but it's actually 10W
/m² for the 2.45 GHz frequency as specified at the top of that page. The 100mW/m² number he pulled is from the section giving examples of common levels you might encounter at home etc, and specifies the maximum exposure that one might encounter for each source, it's not a safety limit. So his own testing actually proves the exact opposite of his claims assuming you trust the WHO.
You might think "oh he just made a simple mistake then", nope if you look through the comments he has directly engaged in conversations with many people that have pointed this out, and has since continued to make several similar videos(only on Apple products) quoting the same bs number regardless. And every video just happens to be monetised and plastered with affiliate links(even to AirPods ?).
Intentionally misleading the public with false facts for profit is both a violation of YouTube terms and illegal.
