Is there evidence of a marked shift away from centralization in network programming?

I’ve heard some new projects are eschewing massive decentralization as a desired outcome, and moving more towards small set P2P networks, given the challenges in moderation, scaling and the evaporating cool effect. Is there any evidence to this, or is it just hearsay? Is the future moving away from FB/Insta/etc and towards easy-to-deploy Discord-alikes for our circles of friends, perhaps all based on open standards and interoperable? Or is this just wishful thinking? I know FB will not go away tomorrow, but in terms of cultural relevance it might be a thing of the past seeing as the average user is older. Thanks for any replies, I welcome your insight.
