The point wasn't that Zuckerberg was already famous, it was that Zuckerberg already has the world's most powerful publicity machine without needing any help from journalists.
(I'm not convinced by the argument, though. 1. Even if Zuckerberg has a better way of getting his chosen message out to people, he still needs a message to get out, and "I'm giving away a ton of money" is a pretty effective message whatever channels it's broadcast on. 2. Many people's reaction to seeing positive coverage of Mark Zuckerberg might be a little more suspicious if the place where they see it is Facebook.)

Has he? If he just programmed Facebook to spam on everybody's feed "Mark Zuckerberg is awesome!!!" I doubt he would have obtained the intended effect.
Mark Zuckerberg annouced that he is going to give away 99% of his facebook wealth ($45 billion) over his lifetime.
He announced guiding questions:
It's interesting that "live much longer and healthier lives" is on the list. Larry Page seems to divert money inside Google into Calico for anti-aging tech. Under Cook Apple also invests into health.
The future seems looking good :)
