The tl;dr is that we live in a multiverse, signing up for cryonics moves your probability mass into worlds in which very few people survive, whereas not signing up moves your probability mass into worlds in which other things make you survive, which are likely to be the sort of thing which make a lot more people survive. Also, surviving via not-cryonics seems better than surviving via cryonics, for reasons I can go into if pressed.
I don’t feel it’s contrived; if I knew that we weren’t living in a multiverse, I don’t think I would have major objections.
My “excuse” was outlined here.
