You could call it decentralized in the sense that the data is hosted in git and anyone can do pull requests to add torrents. But “federated” data storage is tricky because you need some approval / trust method of adding data, otherwise anyone could add a lot of crap / noise to it. This is why most modern torrent trackers / sites have difficult signups.
