It reads to me that AA has clarified that these are surcharges and has not actually collected any money from the passenger yet under the guise of taxes
If AA rebooked the passenger involuntarily onto BA, I would agree that there is no grounds to charge the extra charges, however AA has offered an AA routing for no charge and is stating that it will not offer BA without the supplement which would be a voluntary change initiated by the passenger.
