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.

Fluoroprotein foams exist! But still contain pfas.

The federal government required fluorinated foams for a long time as well, so let's not let them slide.

Only in certain circumstances, as there are fluorine free foams for fuel fires. Water sprayed on other types of fires is (ostensibly) pfas free. Dry chemical mixes also do not contain pfas as an active ingredient.

Yes it is, just tiny amounts.
