I don’t know why. The perception that “FIR filters are always linear-phase” is more apparent in pro audio and hifi audio than in other fields, like telecommunications. It may be due to audio folks historically wanting low-latency minimum-phase filtering which is typically done with IIR filters OR linear-phase filtering which can generally only be done with FIR filters. And therefore the fact that FIR filtering can also do mixed-phase and maximum-phase filtering has not been considered until recently.
