This is laudable - but it ignores the reality of aggregators and user behaviour in the attention economy. The audience is centralised, and increasingly so. The question becomes: how can a pluralistic public-service ecosystem flourish within that economy?
In the UK the BBC has tried a number of routes for this, including sponsoring local reporters, external linking to local news outlets to try and share their audience and so on. None have really been successful but it's important that they keep trying -- and odd that a piece like this wouldn't mention the BBC at all, come to think of it.
