The one thing about ISM is that a lot of those are actually transmitting only; for instance, microwave oven. The fact that amateur radio service needs accept interference from ISM equipments just indicates the fact that hams can't report instances of interferences to FCC (as long as such devices are operating under proper conditions as described under Part 18) and unlicensed services usually receive very little protection, if at all, from interferences caused by licensed services.
