https://git-annex.branchable.com/todo/Bittorrent-like_features/ – Use IPFS as a special git-annex remote, and it will be nearly impossible to execute a take-down.

If you have other “decentralized filesystems” that have “better” behavior than IPFS, you might see if joeyh or yourself can add them as other special remotes.

Given that some films are getting post-release edits before they appear on streaming or physical media, it might be a good idea just from an archival perspective.

I’m not a good judge of piracy methods for consumption, as I am currently willing to pay their prices or do without.

The other suggestions are probably better, but you can technically self-host Wire (from Wire Gmbh) but I’ve never done it successfully.
