PFAS in DWR / water resistant applications is being replaced with silicone-based tech and some other novelties.

PFAS in coated paper goods can be replaced with silicones, sulfuric acid baths, etc.

PFAS in machinery could be replaced with food-grade lubricants like mineral oil, etc. (or just more frequent cleaning)

Give me some other common applications and I'll help think about the alternatives

This is an opinion. "screed" and "lobbying" are not neutral words, they have negative connotations.

>The above makes it sound like people are dropping like flies left and right. There must be a reason why it's still on the market and used widely.

This is also an opinion. It uses hyperbole to cast shade on GP's original words, to imply a dreadful scenario that should be happening if those words are true; you then say, paraphrasing: this scenario is not happening, so then it follows GP's assertions are not true (to be clear: this is your inference, implied, not mine).

This is how I read your comment; I admit, I might've gotten wrong and I apologize if that's the case.
