Facebook started from the assumption that people are basically earnest in their posting. It still clings to that assumption.

But as FB’s share of the information marketplace increases, it attracts the trolls and the misinformation campaigns.
Getting big doesn’t just change the companies opportunities. It also demands a rethinking of fundamental assumptions.
