Google and Facebook have an employee:user ratio of roughly 1,000,000:1. This makes
any hands-on intervention
exceptionally expensive.
(Not impossibly, given high-enough levels of interest, but high.)
Google, and technology's, most powerful tool is its ability to amplify reach, capability, and efficiency. This works very well in a broadcast-style transmission.
Where that transmission is reversed, and the many nodes start trying to feed back to the single hub, there's a problem. It's interesting to note that much of the history of the formation of the modern corporate entity has been one of changing modes of communication (and the parallel development of management structures). Two authors who explore this in (well, for me) fascinating detail are JoAnne Yates and James R. Beniger

In particular, broadcast technologies give leverage, but work best, as with the agricultural model, where seed can be scattered at will, and harvesting is simple, bulk, and commodity. When your plants talk back to you and have concerns about their growing conditions and/or opportunities, you're going to need a more complex feedback system. And it will have to be effective.
This has long been an Achilles' heel of Google (and, to be fair, many other large corporations).
On which, see A.O. Hirschman's Exit, Voice, and Loyalty: Responses to decline in firms, organizations, and states.

The fact that the modern corporation is, by its very intent and design, a risk-externalising machine, one that shifts danger to customers, users, vendors, and employees, rather than either the investor-principles or their manager-agents (and yes: principle-agent problem is another dynamic) is itself part of this very toxic mix.
