That's also a function of lack of strong evidence of harm. We're not even sure that people exposed to high levels of PFAs are suffering harm, let alone the other 99% of us. There's no mesothelioma-level smoking gun here even for firefighters, factory workers, etc., let alone those of us who are only exposed to it via drinking water.

It's a mass hysteria, and while I'm certainly not saying it's benign, I've read the studies, and they remind me of the nutritional ones from the 90's we've all since abandoned where they just throw a bunch of claims at the wall, show a bunch of weak correlations in completely uncontrolled studies, and say "more research is needed".
