Much like proprietary software, the flagship media outlets view news gathering through the lens of proprietary source, only in this case the source generally means access to people, information, data that is not available to laypeople… Conversely, these established sources and experts rely on these relationships to spoon out information and views in an effort to shape a narrative. This is a routine/process/game that has only become more institutionalized [snip]

In the past before open source, stories would run, information would be provided by "sources close to" whatever was happening in the world, and then that was the established narrative. In today's world it is not just that everyone anywhere can post their thoughts, personal experiences, videos/photos, or anything that may or may not contribute. It is also that there is a community of people willing to test the veracity of that information… It becomes essentially impossible for the news to be defined by a private conversation between a "well-placed source" and a reporter…

Finally add to this that often there are true experts on events that are no longer bound by organizations involved who are willing to lend their opinions. It isn't simply the domain knowledge or access to the data, but the checks and balances, and the debate (vigorous as it is) across all those bits and pieces.
