I've read about half of the Cryonics article, the argumentation is fairly bad.

If "SECTION 5: WARRANTIES" was left out, the bio-luddites would have a field day, because then Cryonics would be reduced to nothing more than a fraud. It would have been downright fraudulent to state otherwise.

Second thing, i find that only vitrification is probably good enough, and, IIRC, CI doesn't provide the service because of what people might think (cowards, Alcor has my respect).
