Why would any major WP site integrate a REST API if it means their content is going to be accessed without the gateway of advertisements on their own site? Ya it'd be flipping fantastic if people made aggregators for good sites with the new features, but isn't it a direct conflict with business interests?

All the data in the API was carefully chosen to ensure we don't expose any more than is already. RSS feeds already expose a huge chunk of this.

a REST API doesn't necessarily mean outside access. For one thing, it’s a quick conduit for React and Angular front ends. I've had countless requests for this kind of thing — in fact, this API makes a hacky plugin of my own thankfully obsolete.

Beyond existing sites, the REST API means that Wordpress can be used as a quick-and-dirty back end to datasources that are not necessarily bloggy. Folks use Wordpress for things beyond blogs because they don't want to build custom CMS's, now this CMS has a whole new field of possibilities it can fulfill.

Most people I know are using the REST API as a data provider for other services in their control, not as a public interface.
