Piwigo has an S3 extension https://piwigo.org/ext/extension_view.php?eid=691

Pixelfed and Mastodon have a comparable presentation. Lemmy is a bit different. The focus is different. It might be possible to display content from every fediverse implementation but it might be a less than ideal experience for many of them.

The problem is not the data. Only the central nature and the dependency on a central point.

As pretty as that would be it has its problems. For this to work you need an authentication service. If you use that service for everything then your accounts are linked to this auth provider and you get a problem if that service goes down. You create a single point of failure.

That being said matrix and mastodon support oauth providers. So it is possible to have unified authentication provider for these two. Lemmy doesn’t support this yet.

I read a proposal for the ActivityPub spec for shared groups. It means that a group can essentially be hosted from two instances together. But AFAIK the proposal is not yet approved and it needs to be implemented in lemmy for it to work. Right now a community is gone if the instance is gone.

But they can’t fingerprint you on your home instance. If you don’t use threads they will have a hard time.

Meta can’t track your IP if you post from your home instance. They don’t have access to that.

If someone has a case it is a good idea to apply the laws. But you first have to find you that laws have been broken and by whom.

Indeed if it’s not a mage corp then it’s a government. There is no winning here.

I don’t know how they would profile you? They don’t have your IP and Lemmy doesn’t have trackers. Still it’s best to not post stuff that you don’t want everyone to know. And don’t misunderstand me: I hate that everyone tries to monetize me but that is the world we live in. I don’t know how to change that so I stop moaning.

Maybe it is useful to differentiate between what is legal and what is possible. And even if it not legal it is easy to harvest data from the fediverse. It doesn’t have to be meta. It could be a state government. It is public and everyone should act as if the data is already harvested.

That only works if your profile can be matched to an ad profile.

They could only create a correlation if you let them. If your username is cryptic a ough and you don’t link to all your other social media it will be hard to profile you. And the ads would be on platforms where they can serve ads.

I fear that many people are not aware just how public everything in the fediverse is. Everything you post, every comment, every upvote, boost, favorite, like or other interaction is broadcasted to every instance where there is at least on subscriber/follower. Nothing in the fediverse is private. There is no real way to protect from this. You don’t even need a real instance for that. You could write a software that subscribes to everything and just takes the data. The fediverse is as public as it can be. It’s like standing on a market place and screaming out your thoughts. There is nothing stopping anyone from writing it down. And that is by design.

And I don’t mean that in a negative way. It is not really different from all the commercial platforms. They just take the data without you knowing it. Here you are very aware that you don’t control anything that you do in public.

The solution is to act accordingly. Use cryptic usernames and don’t post anything that can be traced back to you. Be aware that you are in a public space.

Nothing is stopping you. Apart from laws that regulate data collection maybe. IANAL.

I don’t think you will find that but maybe you can find an instance that has similar values to you. Other than that you can only host it yourself.

Mastodon already has solid account migration so I assume this will come to lemmy as well. But at the moment the development focus is more towards stability and performance than features.
