These articles are always feel so silly for anyone in the field. There are literally dozens of papers coming out every week on the subject of PFAS destruction and probably about 10-20% of them are equally "simple".
The problem isn't destroying the C-F bonds, it is doing it efficiently and with enough scalability to process hundreds of tons of soil or lakes worth of water without making a bigger mess than we started with. Most of the common PFAS compounds are going to be tied into CERCLA and the RCRA hazardous substance lists hopefully this year which should mediate further environmental contamination, but we have to make chemical companies do more due diligence regarding chronic exposure risks before they make new compounds mainstream and ubiquitous.
