I suspect they are just referring to the basic social fabric, so to speak. If everybody has a variety of mostly trustworthy sources that act as implicit or explicit verifiers of each other, then everybody has a fairly robust ability to gather information about the world - including the trustworthiness of the various parts of their 'net'.

This sort of thing seems to have, however, somewhat broken down in recently years. At a minimum I think most people would say these networks are at least smaller and more insular than they were in the past.

If it's all in good faith, this might not be so terrible. If the aforementioned trusted CEOs faithfully and accurately are able to point out media they believe is trustworthy and keep an eye on those outlets, it could potentially work as a way to kick start the rejuvenation of these networks.

Now, this relies on these CEOs being both trusted and trustworthy. That is a fairly substantial assumption in my opinion.

But if it's all in good faith it's possible to read this as not Orwellian at all, but rather more informing a section of the community that there is something they can do for the community, and then asking them to do it.
