Most cryobiologists don't know or care about cryonics, because it is the purview of a tiny (< 3000 peple) and eccentric minority.
The Society for Cryobiology doesn't allow cryonicists to become members and has issued statements that describe "cadaver freezing", as currently practiced by cryonicists, as an "act of faith, not science"
Though Fahy is first and foremost a cryobiologist, he has spoken at life extension and cryonics conferences, and he is not at all opposed to seeing his technology used to improve cryonics.
Does he endorse cryonics or is he signed up himself for cryopreservation?
The Society for Cryobiology consists of only ~280 members (by contrast, the Society of Neuroscience has 40,000 members). Furthermore, those ~280 largely specialize in frogs, oocytes, etc.... but not in organ cryopreservation. For whatever it's worth, focus only on organ cryopreservationists and you'll find the percentage of cryonics supporters drastically increase.
I know you skimmed this article, but I encourage you to read it again. There you'll find your answer to Greg Fahy. Also, Brian Wowk is an organ cryopreservationist who supports cryonics. Peter Ma...

Came across it pretty randomly, I found it quite intriguing. Cryonics is "routine" for human embryos, not far-fetched for humans at all. Makes the whole thing seem potentially very reasonable (and me someone who hasn't signed up and doesn't plan to).
