After this came out, a more clickbaity titled article asked vendors if they still have PFA "forever chemicals" in their products: https://www.androidcentral.com/wearables/does-your-fluoroela...

TL;DR: Apple and Google eliminated these, Samsung gave a less clear answer.

>"Over a decade ago, we successfully eliminated two PFAS members — PFAS and PFOA — from our products," Apple told Android Central. "Apple has been working to phase out PFAS from all our products and manufacturing processes, which includes engaging with all of our supply chain partners and developing safer alternatives."

Neat.
