Not sure what the point of "Mastodon's" opinion is? Firstly, Mastodon is pretty big and decentralised, and it has no-one who really speaks on behalf of all its users. Lemmy is not a privacy central network like a direct messenger service. It never claimed to be privacy centric as far as I know. The point is to share posts in communities, and the more that see them, the better.

But it is federated which means posts do get shared to other servers everywhere, and deleting those is not as easy as for a centralised server. Whatever I post on any sharing type service, I consider to be public.

@elbowmacaroni if instead of linking to the post you had boosted it, would all the replies here appear in beehaw?

I think this is a feature, well the media aspect anyway. Immutable media. The rest can be developed on.

So just to clarify this point:

Anything remains visible on federated servers!

If I delete a comment on beehaw.org, it doesn't get deleted when accessed from another Lemmy instance that federates with Beehaw?

Deleted comments remain on the server but hidden to non-admins, the username remains visible

This is a negative behavior by Lemmy, in my opinion. Deleted comments should be purged after some time. Tildes does the same thing - I think with 30 days?

Deleted account usernames remain visible too

These should be replaced with some random string of characters or something like DeleteUser or something.

Anything remains visible on federated servers!

This is just a concession of federation.

When you delete your account, media does not get deleted on any server

This is an issue, too, in my opinion.

Am I missing something or isnt it that no matter what Lemmy does all those same problems would still exist, just from the internet archival sites instead. Sure the privacy could be better to deter some of it, but none of those issues are fully solveable so long as thise archival sites run. I guess the media not deleting is likely the biggest thing you could effect that archives would be less likely to store in the first place.

Kinda unsurprising as rumors have it that lemmy's developed by pro-China Tankies.
