I don't accuse anyone of lying, except a certain President of the USA on some occasions. But manufacturers are sometimes given to hyperbole in their advertising copy, and too, they are sometimes inclined to treat their potential customers as ignorant, such that they feel the need to exaggerate in order to make their point. Like Intactaudio said, an "ideal" current-driven phono would in fact present a zero ohm input Z. So I would say maybe Mr Kimura is exaggerating. I never did any research into the 47 Labs product, but I did read as much as I could find about several others, most of which are far more costly than the 47Labs, and some of which have been given rave reviews (e.g., Aqvox, BMC MCCI, etc), and none of those truly provides zero ohms input impedance, if you read the fine print. But that doesn't lead me to believe they aren't excellent in SQ. In fact, I think that when M Fremer reviewed the BMC MMCI, he indicated its input Z is about 4 ohms. The one I'm using I know for sure does not give zero ohms input Z, but the sound I get from the MC2000 is superb, and that is what counts. I've also used it with another LOMC (AT ART7) that has a 12 ohm internal R. Since my unit's input Z is about 20 ohms, it is operating more like a current drive when I use it with the latter cartridge, and it sounds just as excellent.
