The time evolution of RM and DM is more inclined to be ascribed to local plasma in the host galaxy rather than the intergalactic medium or free electrons in the Milky Way. Recently a sudden drastic RM change was reported for an active repeating FRB 20220529, implying that some kind of mass ejection happened near the source.
