@Hyolobrika@strypey@raphael As far as I know Aether and Freenet are single implementations and fully depend on their developers. Only a few people use them so we don't even know how they scale.
IPFS is owned by Protocol Labs, and there are no independent implementations. IPFS will disappear along with Protocol Labs. Also, after all those years it is still too slow for the web and useless without gateways. Torrents is the only system in your list that is truly decentralized. However, they are only successful because trackers exist
