An intelligence service monitors social media. They may as well have said, “The sky is blue.”

More interesting is,

Sharing as a force multiplier

Do you know of a provider is actually private? The few privacy policies I checked all had something like “We might keep some of your data for some time for anti-abuse or other reasons”…

No, that’s because social media is mostly used for informal communication, not scientific discourse.

I guarantee you that I would not use lemmy any differently if posts were authenticated with private keys than I do now when posts are authenticated by the user instance. And I’m sure most people are the same.

Edit: Also, people can already authenticate the source, by posting a direct link there. Signing wouldn’t really add that much to that.

Sure, but that has little to do with disinformation. Misleading/wrong posts don’t usually spoof the origin - they post the wrong information in their own name. They might lie about the origin of their “information”, sure - but that’s not spoofing.

I don’t understand how this will help deep fake and fake news.

Like, if this post was signed, you would know for sure it was indeed posted by @[email protected], and not by a malicious lemm.ee admin or hacker*. But the signature can’t really guarantee the truthfulness of the content. I could make a signed post that claiming that the Earth is flat - or a deep fake video of NASA’a administrator admitting so.

Maybe I’m missing your point?

(*) unless the hacker hacked me directly

It works fine for me on Hyprland.
