He's very much part of PAF https://fr.wikipedia.org/wiki/Paysage_audiovisuel_fran%C3%A7... ... but indeed as you point that might be totally irrelevant today.

FIP is cool, I even have a shortcut to play/pause it from anywhere on my system using 'mpv https://stream.radiofrance.fr/fip/fip.m3u8 --no-resume-playback'

That's funny you're referring to "PAF" because it was a confusing word for me for a long time: it was used for this purpose, but also the "PAF" (as Participation aux frais) written on events flyers. Trying to find their meaning while thinking they were the same word...
