The article doesn't mention (other than a brief nod to the brand) the other massive use of PTFE, none sticks surfaces originally under the Teflon brand, most commonly found on cookware. It truly is a "magic" material.
Teflon and other PTFE based none stick surfaces are now really quite controversial due to the toxic gasses they can give off of you heat them too high. And the manufacturing processes is potentially linked to a higher risk of cancer for workers.
The industry is now moving away from PTFE to other materials for none stick surfaces, however although they proclaim these are "safe", they have been studied far less. I believe some evidence is indicative of them also having serious issues.
