I assume it's simpler to outlaw all downforce increasing systems than just one specific one, thus making them all illegal. Of course, it creates its own set of problems since there are a large number of transient situations where downforce is increased temporarily, like landing after popping a wheelie, etc. Most of these are usually offset by decreased downforce at other times, of course, but that doesn't seem to be taken into consideration in any of the rulings.
