Among all the ways of interpreting society’s generalized angst at Mark Zuckerberg, the most helpful, I think, is becoming the call for more publicly supported media. See, e.g., this CIGI piece.
I’ve been known to spout off about the corrupting effects of new media on democracies here on the blog. Public media is one route you could take from here, so is banning advertising in the news (i.e., everyone is a subscription model), licensing web media sources, hiring the truth panels and suppressing misleading sources on Google and Facebook. You could probably come up with your own list.
