I agree. (And, in the other direction but I think probably much less important, if the press responds with uncritical adulation when a billionaire gives the impression that he's giving away lots of money, without anyone checking what he's actually doing with it and whether it'll do any good, that incentivizes donating billionaires not to bother making their donations actually do much good.)
without anyone checking what he's actually doing with it
The articles that were linked above don't do that. If you would want to do that you would look at Mark Zuckerberg's past record with his donations towards education. That would need actual work on the part of the journalists. It's much easier to do the kind of criticism where you focus on the future and speak about possible future problems.
It worthwhile for journalists to check in a year what the Chen Zuckerberg Initiative actually did but now it's time to celebrate.
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 :)
