The server can swap to a modified JS that exfiltrates the e2ee key and thus allows the server owner to decrypt the messages, or in more advanced encryption schemes add additional keys without you knowing and achieve the same thing.

Yes you can juryrig something like that with cookies, but it is highly fragile and browser based e2ee is basically a scam anyways as the server serving the website can always swap out the javascript that decrypts the messages.

e2ee is not really compatible with what you want due to necessary key management, and once you drop that there are so many possible options for what you want that I don’t want to list them all here.

/me notes the commenter’s home instance and concludes there is no point in arguing about this very biased take…

Maybe it was based on the “lifetime” of their hamster 🤷

You need to set it to proxy all images.

The currently common older implementation of e2ee in xmpp has the same issue with only the message body being encrypted. There are newer specs of OMEMO that have better metadata protection, but its adoption in xmpp clients has been very slow.

Prosody is more of a sandbox, with Snikket being a preconfigured version of it, but yes running Slidge will be a bit easier with a normal Prosody server.

Then you have not enabled to full image proxy (and note that it does not work retroactively). Here on our instance all the Nicole images were proxied correctly to protect the privacy of our members.

Today xmpp uses a distant relative of those original jingle specifications, which have been modernized to use Webrtc.

Lemmy does have a functional image proxy, but due to the storage and bandwidth requirements many larger instances have chosen to not enable it.

Xmpp is mostly used for private groups and 1:1 chat, so more of a WhatsApp than a Discord replacement.

But you can find some public channels here: https://search.jabber.network/

The issues you mentioned have been fixed, and XML was never an issue 😅

Jitsi-meet is already using xmpp under the hood.

But there are some efforts to add multi-user video calls to full xmpp clients as well. Dino can already do it for a while, and Movim and Libervia recently added experimental support.

Its not quite a full Discord replacement, but for private groups it works quite well.

Why would you down-grade from Snikket to Matrix?

If you want to skill up a bit add a Slidge.im gateway to your Snikket xmpp server to access Matrix (and Discord etc.) from there.

Jitsi-meet does that. Easy to install as well.

Yes, in theory, but in praxis no because self-hosting the sync server alone still depends on the centralized auth server from Mozilla, and self-hosting that as well is possible but complicated. It’s sadly a mess, and you might be better off not using Firefox sync at all.

As for your other question, depends on the specific addon, but usually no.

The cheapest way would be to buy a domain from OVH and use their free offer of a 5gb single email address that is included with each domain.

You still need to log into their servers and thus provide them a lot of meta-data, like IP addresses, when and approximatly where you are using your browser, on how many devices etc.

Tagging @rimu@piefed.social as mentions don’t work in post bodies, only in comments.

Would be interesting indeed to have a database migration script or so.

My understanding is that these groups are separate from the normal Pixelfed feed.

First of all that’s all hypothetical and secondly that thought experiment only talks about an app that uses the PDS as an auth source and data storage. It does not talk about your PDS communicating with another PDS, for which AFAIK a relay is needed.
