SNCF staff member told him to switch his phone's loud speaker off, or risk being fined. When he argued, he was served with the €150 fine I'm good with this. He wasn't told to end the call but to stop subjecting passengers to both sides of a loud phone call. Using his phone like a phone would mute one end of the call and likely quiet the other. It's bare minimum not-jerk behavior.
