I really doubt it has much to do with messaging at all. It's more about the ability to disseminate and control messages the public sees, especially in a "narrowcasted" way.

Think creatively here, it's not just going to be Chinese flags overlaid on everything. Just amplifying stupid/criminal/vulgar/etc. content (more than the internet already does) could have a subtle but significant negative effect.
