With the lofty claims of "health risks", I was disappointed to find no sources linked at the bottom of this article (correct me if I'm wrong).
Based on my personal experience, I think "health risk" is an overstatement: bad PWM can be uncomfortable (Geneva Airport had particularly egregious lights that started flickering in your peripheral vision), but I doubt there are any long-term effects of it.
Reading further down, a few other comments [1][2] have stated this better than me.
I'm interested in this topic and stay on top of most threads/discussions about PWM.

I would have thought the same, but it seems to be a common experience that once someone becomes PWM sensitive it actually sticks with them.
I've been a techy my whole life; the iPhone 12 mini seemed to be the device that triggered my PWM sensitivity and since then I have been extremely sensitive to any device with PWM.
Although I have tried to keep PWM devices out of my life, I can still quickly tell when the TV in a lobby or the airplane entertainment display has PWM and there's not much you can do about it.
