Anyone else sees has a problem with this particular statement taken from Cryonics institute FAQ?

One thing we can guarantee is that if you don't sign up for cryonics is that you will have no chance at all of coming back.

I mean, marketing something as one shot that might hopefully delay (or prevent) death, is hard to swallow, but I can cope with that, but this statement reads like cryonics is the one and only possible way to do that.
