The possible upside of this may be the decentralization of massive content silos like youtube or facebook, toward federated or self-hosting platforms where the administrators of individual "sites" can better know their users. I can see the "fediverse" (the main public ActivityPub network, notably including most Mastodon users) benefiting from this, for example, since a club/gaming clan/media company could run their own Mastodon instance and be responsible for the things posted using it.
