Facebook wants to solidify being a content portal for news. Its competition is Google with AMP, Google and other search engines without AMP, and first-party content producers, and 'orthodox news aggregators'. Both Facebook and Google have an advantage: they have hyperlocal info and tons of data on users collected through their tracking and ad networks, they are two of the most-visited websites and most-used apps in the world; meanwhile they subsume all the advantages of an old-style news aggregator by having a wide variety of third-party content they never had to pay for.

'Emerging business models': Facebook is a large IdP containing identities that they monetize through data mining with the goal of display ads. But this IdP allows their users to log in to other sites and engage in microtransaction-like behavior. Aside from making actual payments to FB, users could trade off 'ad credits' or whatnot. Flattr, Webpass are in this space; Google tried this with Contributor [1], which is about to see a revamp; Brendan Eich is trying this with Brave, but Facebook's install base and ability to focus and deliver means they could probably pull this off better than everyone else.
