why haven't they tested this on animals or non-paying cadavers? It would seem unwise to pay to keep vitrified bodies frozen if one had no understanding of how the bodies would be when they were unfrozen.
Apparently the bottleneck is in thawing organs past a certain size, current thawing methods lead to uneven thawing in larger organs, however I read they were experimenting with using directed radio waves?
Of course once you thaw a person successfully you still need to cure them of what killed them and revive them and that part is highly variable and if they died of aging is still well beyond our reach.

With proper storage maintenance vitrifified organs can be stored indefinitely while frozen things eventually get freezer burn.
Imagine if I made an origami animal, then unfolded the paper and handed you the paper plus an origami book with the animal I made. With enough time and care, you'd probably be able to observe the creases and refold the paper to reconstruct the original animal.
Supposing technology continues to advance at the rate it has been -- then by year 3000, the problem of cryonic revival is likely one of statistical inference on possible original brains, with the cryopreserved brain as evidence. Hard to predict the difficulty of that problem in advance.
Source? How do you know it's not just the neurons?
The people storing popsicles don't necessarily need to have anything to do with the people who dream of someday unthawing them. If some rich person wants to pay to keep an expensive freezer running for a specified amount of time after they die, that creates a sound business opportunity for someone who is willing and capable of running a freezer.
Generally speaking the thing they have in common is the funding required to do the cryonic enterprise.

The question is "why would some rich person want to pay to keep a freezer running after they die?" in the case of cryonics the answer is usually because they have some expectation that they could be unfrozen and revived in the future.
Once we can successfully Futurama the bodies we will easily be able to retrieve the frozen capsules.
The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins (−270 °C; −455 °F). Probably too cold.
How many times have you said "sod it, that sounds like a problem that Tomorrow chordalkeyboard can deal with, I'm going home"?
In this case, it's "sod it, future human-popsicleologists can solve that one, at least I got them frozen"
