Took baby to chiropractor

This literally angers me and idk how to handle it. Someone I know took their newborn baby to a chiropractor because baby has been “whining” a lot. Of course, that’s what babies do!!! But the thing is, this baby is actually perfect. Parents are not even sleep deprived because baby is sleeping through the night and has to be woken up to feed. Baby only cries during diapering or bathing, maybe an occasional tummy pain. There is absolutely no reason baby should’ve seen a chiropractor. I am actually dumbfounded at this situation and these parents don’t realize how lucky they have it with this newborn. I don’t want to overstep my boundary but also wtf?!!
