Signal isn’t federated [1][2][3.1]; it’s decentralized [1][2][3.2]. Though, for all practical purposes, I would generally argue that it’s centralized.

Signal relies on centralized servers that are maintained by Signal Messenger. In addition to routing Signal’s messages, the servers also facilitate the discovery of contacts who are also registered Signal users and the automatic exchange of users’ public keys. […]

One of the controversial things we did with Signal early on was to build it as an unfederated service. Nothing about any of the protocols we’ve developed requires centralization; it’s entirely possible to build a federated Signal Protocol-based messenger, but I no longer believe that it is possible to build a competitive federated messenger at all. […] [interoperable protocols] [have] taken us pretty far, but it’s undeniable that once you federate your protocol, it becomes very difficult to make changes. And right now, at the application level, things that stand still don’t fare very well in a world where the ecosystem is moving. […] Early on, I thought we’d federate Signal once its velocity had subsided. Now I realize that things will probably never slow down, and if anything the velocity of the entire landscape seems to be steadily increasing.
- ¶“Stuck in time”. “Federation and control”. ¶6.
An open source infrastructure for a centralized network now provides almost the same level of control as federated protocols, without giving up the ability to adapt. If a centralized provider with an open source infrastructure ever makes horrible changes, those that disagree have the software they need to run their own alternative instead. It may not be as beautiful as federation, but at this point it seems that it will have to do.

Yeah. I love Signal but it doesn’t belong in that list. Dansup (creator of loops and pixelfed) is apparently working on “Sup” that will be a decentralized alternative to whatsapp.
To me this person sounds like they have too many big projects at once. I wish them success tho
Yeah… I’m bit afraid of “kbin Ernest Effect” (not sure what a proper term is) where personal issues pile up and the sole head developer just disappears.
Haven’t followed dansup much but from what I understand he is much more open to pull requests and listening to the community, but time will tell. Right now I appreciate and love his effort, giving, and the impact on fediverse he is brining.
The kickstarter was a good idea.
Delta.chat already exists
Matrix?
Bro put citations in his lemmy comment 💀
I wish more people did that ngl 💀
I wish Boost understood the collapsible spoilers.
On my client, it’s all expanded and I see all the formatting characters. It looks/works great in a browser though.
but I no longer believe that it is possible to build a competitive federated messenger at all.
The fact that we have a telephone system that works with separate providers contradicts this sentiment. If I want to pick up the phone and talk to my cousin’s puppy in New Zealand, I can do that without creating an account on his provider’s service.
I don’t understand why we’ve forgotten this as a society. Yes, it was difficult to upgrade the phone systems over the past century, but it’s worth it in my opinion. I really wish we’d start seeing government regulation that says “you should be able to talk to someone on a service without having to create an account on said service.” I thought the DMA would do this, but sadly, Whatsapp still requires an account to talk to people using that service. Very disappointing.
Don’t let perfect be the enemy of good
My comment wasn’t protesting the use of Signal; it was rather clarifying the misinformation in OP’s post — ie misinformation that Signal is a federated service.

For the avid readers out there, bookwyrm is a fantastic alternative to goodreads.
Yes it’s excellent! Also noting for those that aren’t aware: Goodreads is owned by Amazon.
Is there a way to automatically add books to it when a book in my Calibre Library gets marked as completed?
Unfortunately, the switch from YouTube to PeerTube has not worked for me so far. I can’t find a decent instance (not full of right-wing/conspiracy content) with interesting stuff that also allows me to make an account.
Yes finding the right instance on peertube is a nightmare — and also the general lack of quality content, or subtitling, which makes it as good as useless for deaf people like me.
Signal is not Fediverse! Element/Matrix is!
Element/matrix aren’t part of the fediverse, either. It doesn’t speak AP.
Matrix is federated, Signal is not.
although it is federated, it isn’t apart of the fediverse, as it doesn’t use activitypub.
I’d argue it’s part of “the fediverse” but not “The Fediverse”.
Are we claiming now that Activity Pub is the only protocol that we can use for the fediverse? I think XMPP is roughly 30 years old at this point, and I’m pretty sure Activity Pub is much younger than that. I could be wrong though.
But regardless, I don’t see why Activity Pub has to be the only protocol we accept to be considered a part of the fediverse. It’s not even like different AP implementations talk to each other all that well. My understanding is that Mastodon doesn’t federate that well with Lemmy, and I haven’t seen Loops or Pixelfed on Lemmy yet either.
I’d be happy to be corrected on any of this though, I haven’t looked too closely into exactly how AP works or how it’s supposed to interoperate with different applications.
Don’t use Matrix the devs knew about sidechannel vulnerabilities and ignored them for years. This is peak negligence and should immediately disqualify you from touching anything security related.
the author literally picked random projects from github tagged as matrix, without considering their prevalence or whether they are actually maintained etc.
if you actually look at % of impacted clients, it’s tiny.
meanwhile, it is very unclear that any sidechannel attack on a libolm based client is practical over the network (which is why we didn’t fix this years ago). After all, the limited primitives are commented on in the readme and https://github.com/matrix-org/olm/issues/3 since day 1.

PeerTube appears to be completely devoid of content
A federated social fitness app(like Strava) would be cool
Ok, downloaded peertube (because to hell with Google and YouTube) looked around… Um, is there not too much to look at right now? Are the people I normally watch on YouTube unable to be seen on peertube? Don’t get me wrong, all about decentralized everything but if the people I like aren’t there I’m feeling a bit up a creek.
Or, more likely, am I missing something? Forgive me, please, I am rather new to this concept and how to work the federations and such.
Great graphic! The only things I use on this list are reddit and youtube. Trying peertube now. I’m confused about whatsapp and facebook messenger - don’t people just use the texting app that comes with their phone?
Ah. I see…

I don’t get the joke
Don’t worry, your successor isn’t offering anything big. You’ll still be around for many more days to come.
FB Marketplace --> Flohmarkt is missing!
Unpopular Opinion Lemmy and PeerTube logo look ugly.
Unpopular opinion: your opinion is not unpopular at all.
Facebook Marketplace - > Craigslist
I’ve been on Signal for a while now. Have a bunch of groups but iMessage works with everyone.
It’s been a year and a half here on Lemmy. I still spend a lot of time on Reddit, but won’t comment there anymore.
I don’t WANT a Twitter replacement as it’s really only for celebs and idgaf.
I actually see enough value to pay for YT premium (kids complain incessantly about ads).
Friendica doesn’t seem to have an iOS app, and there’s a critical mass issue with wanting to connect with people that I know in real life.
I’m trying to get my Pixelfed feed to be with checking, and trying to be a regular poster, but it’s still REALLY sparse, and none of these offer the endless meme-video-clip scroll that my wife will have to have before switching away from Insta.
Anyone know if loops has a good app out, or if there’s one in the works thats coming out soon?
as i say peertube is currently a alt to twitch as well as youtube
