Q. Let the users decide what they see, not the instance owners.

A. #activitypub implementations (mastodon) are federated client-server networks. Files/messages are stored on central servers were the admins and sysamins are legally responsible. If the user's are in charge they could get the Admins thrown in jail for infringing content. A "trust" based network.

Full P2P would give you choices you wont... mastodon etc are "step away" projects. Building "trust" networks is a positive first step.
