The sad part is, no one cares about GA IFR aircraft under A100 except the operators themselves anyway. ASA certainly don't, their contribution to the Navcharge coffers is so minuscule in the grand scheme of things as to be irrelevant. The decision is made so suck it up. It's coming, for the benefit of every airspace user. If the little guys go under because they can't afford to upgrade, stiff. If private IFR has to go VFR or stay home, stiff.
Don't shoot the messenger.
