I'm sure any profit they make is redirected back into the organization's mission.

I still don't get by which virtue they can decide to sell TLDs for 1 million dollars or any other large sum of money. We just ended up having big companies like Google register .google, etc, and random questionable companies register, e.g., .law, .plumbing, etc, presumably for profit. I'm sure ICANN could do better than this.
