They all sell fluorine free foams, so they'd still make money.

Studies at the Naval Research Labs have shown that fluorinated foams just perform better, and for a while, the US govt (particularly DoD) required fluorinated foams. That's changing, but the performance differences have slowed the change to fluorine free versions.

I don't think I'd mind PFAs being used during, say, war time.

It's the fact that they practice with them all the time.
