The more one reads into chemistries of chemical companies, the more one gets scarred.
I was reading into halex chemistry for which this business is the only manufacturer and I was not happy about the effects of these.

This is certainly a niche and not an easy chemistry. However, mild and general synthetic methods for the preparation of aromatic fluorides are lacking, and traditional methods used to generate them, such as the Balz–Schiemann reaction and the Halex process, typically require harsh conditions, curtailing functional group compatibility and requiring fluorine installation at an early stage in the synthesis.
Largely as a result of their unique biological properties, organofluorine compounds have consistently found their place among top-selling pharmaceuticals and agrochemicals. In particular, substituting a hydrogen atom of an aromatic ring with fluorine can retard oxidative metabolic pathways, thereby effectively increasing the lifetime of an administered therapeutic.
