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.
