For alcor atleast, the people in charge of the money are REQUIRED to be signed up for cryonics and I believe 3 of them need to have close relatives or significant others already in cryonics. This means that's it's in the interest of the people in charge to not screw themselves or the people they love, instead of not screwing random frozen strangers.
(nods) I know, and I think that's cool.
Of course, if I run a cemetery and I have close relatives buried in that cemetery I'm probably motivated not to plow the whole thing over to put up condos, and I'm probably motivated to ensure that my own relatives aren't disinterred to make room for new paying customers, but that doesn't necessarily make me equally motivated to ensure the same for people I don't know.
(Caveat: I keep using the cemetery analogy, not because I think it's particularly close, but because I suspect that if I raise these sorts of questions ...
So, apparently appsumo is having a custom reddit bundle, a bundle meant to appeal to redditors, and 10% of the proceeds get donated. On the surface, doesn't sound _that_ interesting, except...
Take a closer look: http://appsumo.com/reddit-special-deal/ and find that the recipient of the donations will be... SENS!
I find this to be an interesting development. It wasn't the "custom transhumanist bundle" or "the custom sens bundle" but "the custom reddit bundle". Yes, "reddit" doesn't, in and of itself, count as extremely mainstream as such, but I'd say it's still an interesting development.
