Alcor and CI are both 501(c)(3) nonprofits. From the IRS guide to applying for tax-exempt status:

A 501(c)(3) organization:

...

• must ensure that its earnings do not inure to the benefit of any private shareholder or individual;

• must not operate for the benefit of private interests such as those of its founder, the founder’s family, its shareholders or persons controlled by such interests;

The only people making money off this are the employees (all 15 of them between CI and Alcor) and the life insurance companies. The rest of us have to settle for a warm fuzzy feeling when people sign up.

ETA: Correction. CI is not a 501(c)(3), just a regular nonprofit. Thanks ciphergoth.
