That’s not how ActivityPub works.

What are some reasons as to why I would want to use this over, say, OSMAnd?

Osmand isn’t fully free software. Some parts are under CC Non-Commercial license that forbids derivatives to make life harder for potential forks: https://github.com/osmandapp/OsmAnd/blob/master/LICENSE#L39 That’s both against the Open Source Definition and Free Software.

Baffled those exist.

Google Talk was never Jabber. The Google Jabber integration was way before that in Gmail. Google Talk was what came after Google decided to abandon Jabber.

Wikipedia says otherwise.

If Google had actually supported Jabber instead of sabotaging it, we would not have this discussion.

Google kills messaging services all the time and launches new, incompatible ones. Google did not sabotage Jabber, they sabotage their own chat services all the time.

It’s not dead, and works fine.

Also WhatsApp is using a slightly modified version of XMPP

Obviously modified enough to work better with mobile when it launched than Jabber’s state of the art back then.

Again: Google did not kill Jabber. Jabber achieved its downfall on its own by being bettered by proprietary services that just worked better on mobile devices BACK THEN.

Well, Monal on iOS doesn’t work worse than Telegram on iOS, so then apparently it’s flawless as well.

Again: The current state is irrelevant when discussing the time frame when Google allegedly killed it. The state of Jabber and its clients was just abhorrently bad back in the day. That was the reason the world moved to WhatsApp. Google Talk has always been a niche product. That’s why it’s dead.

That’s a bad implementation then. Modern open-source XMPP works great on mobile

The issue was the state of mobile clients when XMPP died in the mainstream and state of the art was crap like Xabber. Conversations was better but too little, too late.

iOS is more of a mixed bag, but that is solely Apple’s fault and applies to all messengers other than iMessage.

Telegram works flawlessly pretty much everywhere, including iOS which my mom uses.

XMPP as used in the enterprise communication product my employer uses (AFAIK based on the common open source implementation) sucks as much on mobile as Xabber which I used back in the day. I get notifications 30 minutes late if at all. That thing killed itself by not adapting to smartphones.

Truth Social is a Mastodon server. Does this count during the upcoming Trump presidency?

WhatsApp is the world’s most widely used messenger. FB Messenger (which is now its own product for whatever reason) is also extremely successful.

If Google killed XMPP, how come some enterprise communication products (off the top of my head I can name two that are successful at least in Europe) use it?

If I can follow some mainstream entertainment accounts from Mastodon, I’m fine with that. I dislike having to log onto Twitter or Threads just to find out what some motorsports teams are up to.

When you visit a Lemmy community, only its home server displays the actual subscriber number. If you visit the community from a different server, it shows only the number of subscribers from your server. That’s the reason I put one of those subscriber count badges in the side bar, so everyone can see the correct number.

Several months to a year. ActivityPub support is just in private testing.

That’s built into lemmy itself. If they want to be drastic about it they could fork it out I guess.

Instances running slightly patched versions of Lemmy is nothing uncommon.

It’s entirely possible they got a threat letter from one or more publications about the topic and are doing it to avoid litigation.

I kinda get posting the entire article in the post body but not linking to archives. Publications should then litigate against those archives if they think that archiving is illegal. It’s not like archiving services operate “in the shadows” or anything like that.

Rule 1: “Do not post entire articles or archive links to copyrighted articles”

Also lemmy.world when creating a post: “Why not use one of these archive shortcuts?”

Heard it works well. Didn’t try myself, though.

However: you are not a company that profits from vast amounts of data ingestion.

The entire current Fediverse isn’t vast data by Meta, Google, Microsoft, and Apple standards.

If that’s the attitude, be hostile and have no empathy for someone who outright says it’s his fault but who’s also overworked, then why not sue? Seems that’s the attitude you’re projecting.
