That is true. And the "amorphous" comment holds for any teacher. Had you really investigated his stuff (which I get the feeling you haven't) you'd probably have gone further. Chia's books contain a lot of repetition and in aggregate are confusing to follow. Some even contain such gibberish as claiming that water has a "crystalline structure". In my experience it's difficult to find a competent teacher who actually understands (and can teach) the overall system. However, the Microcosmic and Macrocosmic Orbits are effective as can be discovered with a day or two's effort and are widely referenced in much older sources as the Lesser and Greater Water Wheels/Heavenly Cycles. So it'd be unwise to throw the baby out with the bath water on account of someone being a businessman. The Fusion practices are interesting and insightful if done correctly and the Kan & Li meditations also appears effective (but I'm still exploring them). The Kan & Li is the mainstay of internal alchemy and is widely discussed in a variety of far older texts , so I doubt he's made that one up either.
Michael Winn talks about how the Communist government gutted qi gong of its spiritual practices and that TCM is diluted as a result (one of your articles mentions a clampdown on it too). I believe Winn's been to China several times and has studied with a variety of teachers apart from Chia. His stuff stacks up so I'm inclined to believe him.
While it's fine to reference older texts though, no one has a monopoly on our nervous systems. For me, the only thing that matters is efficacy regardless of lineage/culture. I don't care for names, superstitions, mythologies or rituals - I only seek (and keep hold of) what works for me. We are incredibly fortunate to live at a time when formerly secret knowledge is widely available. I would encourage the astute student to also study cross-culturally in order to find the most effective, personally verifiable practices available given today's opportunities for research.
