Sorry, but PTFE (polytetrafluoroethylene) may be a PFAS (per-and polyfluoroalkyl substances but not a Perfluorooctane Sulfonate PFOAS) however, it is definitely not a PFOA (perfluorooctanoic acid).
Your link does not contain a reference to PTFE and looking at the meaning of the acronyms should provide evidence fluorethylene is not a sulfonate or an octanoic acid.
The manufacture of PTFE may involve generating these as bio-hazardous byproducts and PTFE could be contaminated or even break down into them, but they are chemically not the same.
