"The earth is not a sump into which hum, buzz, and RFI is poured!"

I think what's going on is that "current sink" means different things to different people. I regard ground as an RF current sink, but not one of zero impedance. That means that when a wire with current passing by is connected to it, not all of the current in the wire will be shunted to ground. A low-impedance ground will divert more current than a high-impedance ground.
