They're non-profits, I wouldn't necessarily call them charities, as I meant it. But that's a semantic point. I think people are disinclined to trust them, because they're still asking for people's money. If you could build a system where cryonics would be funded by someone (or someones) else and then donated to another recipient, I think that would make people give it far more serious consideration.

Also, I don't necessarily think Alcor and CI are perceived (which is what matters) as non-profits. I thought they were for profit companies until I started researching this post and read otherwise.
