And carcinogenic as fuck. "Seasoning" is basically plastic made from burnt oil with constituents including acrylamides. Why not cook on less toxic surfaces that are clean?

If your worried about acrylamides then you should not be browning any starchy foods. A lot cooking intentionally wants the Maillard reaction for flavor and texture reasons. When it comes to seasoning carbon steel you should not be letting carbon build up. It's a bad habit. If your getting carbon build up clean it off with something coarse like salt or a metal scrubber. After that if you need to it's not hard to give…

You can smooth out a cast iron cook surface. It only tales a few seconds with a flapper wheel on an angle grinder.

They could be sitting on ten years of supply.

We learned around 2020 that wasn't the case.

Did we? 2020 data is useless and irrelevant anyway since the governmental efforts to stop its production came later, corresponding with industry efforts to bulk up its production before the governmental pressure took effect.

Wish I'd thought of that; I spent a couple hours at it using an orbital sander, up to 320 grit. No regrets though, that pan is easily my favorite piece of cook ware.

Silicones are common food additives, including use as an anti-foaming agent in frying oil. If you are trying to avoid them, you may rethink having those fries next time you are at the drive through. They are also used almost everywhere around us... shampoos, lotions, cleaning agents, cosmetics, medical implants, electronics, lubricants, etc. It seems a few ppm improves every kind of product.

What is the ppm emitted of siloxanes or silicone-equivalents from frying oil?

What is the ppm emitted rate from shampoos?

Simply declaring the presence of a contaminant in other goods is not a meaningful contribution here.

A fascinating display of confidence unburdened by evidence. Basically the intellectual equivalent of arguing that gravity “probably took a few years to kick in.”

Are you actually saying that companies were predicting government regulation years in advance and preemptively cranking out bulk PFAS-coated paper just in case? Because, of course, that’s what every industry does: mass-produce soon-to-be-banned chemicals for fun and profit.
