Adam, how can you possibly say you're not "for-profit" when in fact that is precisely what Blockstream is? do you seriously expect us to believe that Reid Hoffman, et al invested $21M while not expecting at least a 10x return on their investment?
I read somewhere that they invested personally instead of via organized venture funds specifically because they are bitcoin supporters and the investment didn't really meet the usual criteria for the funds (roughly described by you as a 10x return). I can't vouch for any of this being actually true or relevant, but I did read it.
