why should stainless steel require pfas?

To provide additional resistance to corrosion/staining.

That sounds unlikely. It's not how stainless steel works; to bond a coating to the surface of the stainless you have to fight the stainlessness pretty hard.

why should stainless steel require pfas?

Stainless steel is expensive, roughly a factor of 10 compared to plain steel. The reason is that Chromium is expensive. You can use low-chromium not-so-stainless steel if you then coat it with transparent paint containing among other things, PFAS, and save a ton of money on the material.

Edit: the prototypical stainless steel is Cr/Ni 18/10 with 18% chromium and 10% nickel, aka V2A or 1.4301

Consumer solutions for saving the planet result in greenwashing (distraction from actual meaningful change), new poisons, and growing waste through growing demand. Ecology isn't simply making correct purchasing decisions even if they feel good.
