In other words, your post may still be visible on, say, a linked Mastodon server, even if you decide to delete it with Threads.

“I think this is a downside of the protocol that we use today, but I think it’s important to let people know that if you post something and another server grabs a copy, we can’t necessarily enforce it,” Cottle says.

… it’s not a downside of the protocol, it’s just a literal impossibility. Once someone’s downloaded something, you can’t do a thing to take it back.

Yeaa, that sounds pretty likely. If that ends up being the case, then defederation might make sense.

I hope it very much doesn’t get defederated. Meta’s service would have less of a lock-in effect if it could communicate with other servers. The primary reason people stick to platforms like Facebook & co. is that their friends and family are on it; but if they can keep talking to them on a different platform, they’re suddenly much more susceptible to ditching Meta and ditching apathy in regards to privacy.

Be seemingly friendly to Meta and any other social media company that starts using ActivityPub — so that we can get normies to ditch them and join the libre side. :)

(ofc, this position is on a case-by-case basis and hinges on how exactly federation is handled by the service at hand. We’ll see!)

Lemmy isn’t a site, it’s a piece of server-software. The software is written by a couple of people with bad political opinions, who also run a popular site using that software, Lemmy.ml.

You can skip using Lemmy.ml and just use another server using this software. The software itself isn’t magically poisoned or anything!

From what I understand, one of the core devs (Dessalines) is a Marxist-Lenninist; they later founded the second Lemmy instance, Lemmygrad.ml.

Recently, there was some discussion on Lemmy.ml’s (the first and official-ish instance) policy of banning any crticisms of China’s government (e.g., even mentioning the Uyghur genocide) on their own servers.
