I think there ought to be a data/interface divide. Social media companies that service more than 50 million Americans should be subject to this divide. Therefore, split Facebook in twain: one of its halves shall be Face, which is the web UI we currently interact with; the other half shall be Book, more akin to a data utility provider.

The monopoly that Facebook, Google, etc. have is a monopoly over how their data is presented. Google is the only entity with access to the data that Google collates, etc.; except that this isn't data they generate. It's data they capture, pieces of the commons that they sequester from the commons.
