Proč už nevěřím Telegramu
Je to deset let, co jsem začal používat Telegram. Za tu dobu jsem přesvědčil hodně lidí, aby ho začali používat, obhajoval jsem ho, ale v poslední době mám čím dál větší pocit, že jsem se v něm mýlil. V tomto blogpostu se pokusím vysvětlit proč.

Everyone is now realizing that WhatsApp is evolving towards its latest form (archive.md/L3W74). If you value secure messaging, you may want to check out @signalapp or @matrix (wich is #federated). EPFL also has its own Matrix instance at matrix.epfl.ch (use @element as a client).

Aunque el objetivo del vídeo es dejar a #WhatsApp en evidencia, también otorgo una parte no-despreciable del vídeo a #Signal, como la gran alternativa.
También nombro a #XMPP (vivo amenazado por la furia de @kyva), PERO:
Signal es el único "quita-y-pon" 🧩 que tenemos ahora mismo, para seguir conversando con **nuestros contactos telefónicos**, sin tener que ir preguntando a todo quisqui por su dirección.
Que ya los iremos metiendo en el saco federado, pero tú estate en Signal mientrastanto. 😉
Hice un vídeo para que puedas enviárselo a tus personas cercanas, explicando lo fácil que es dejar #WhatsApp, y por qué es importante hacerlo. 💬

Congrats on the release! Anytime a Linux GUI app gets more beautiful, that means a great deal to all the non-geeky users of the world, where aesthetics and convenience are king. I just hope it stops short of getting bloated and slow - witness the sluggish Node.js horror show that the #Signal desktop client is, in #Linux.
BTW: What version of OMEMO does Gajim support? Does the website or documentation say this anywhere?
#Signal for iOS v7.65 release notes:
* Message status indicators (sent, delivered, etc.) are now supported by the iOS VoiceOver feature in order to improve accessibility for blind and low-vision individuals.

> Signal groups, in particular, are more powerful than you might be aware of, even if you already use them all the time. In this post I'll show you how to:
- Turn an in-person meeting into a Signal group using QR codes
- Manage large semi-public groups while still vetting new members
- Make announcement-only groups, perfect for volunteer networks rapidly responding to things like ICE raids

#deltachat is secure against server-side group membership changes but for a very different reason than #signal which keeps encrypted group membership data in a central store.
Delta Chat has _no_ central store but implements a rigidly tested #p2p group membership model where servers play no role github.com/chatmail/models/tre…
Both signal and delta chat are safe against recently published attacks against #whatsapp that can add members to chats, breaking end to end encryption. arstechnica.com/security/2025/…
The weakness creates the possibility of an insider or hacker adding rogue members.Dan Goodin (Ars Technica)
#ElementX nutze ich schon länger parallel zu #Element für meine Chats.
Nun habe ich aber das neue #SchildiChat Next ausprobiert.
Es basiert auch auf ElementX, hat aber #Spaces integriert. Das gefällt mir sehr gut. Damit lassen sich z.B. Chaträume übersichtlich ordnen.
#Matrix ist für mich nach wie vor ne gute Sache. Ich würde es auch WhatsApp-Wechslern eher empfehlen als #Signal ... vor allem auch, weil man sich damit nicht vom Smartphone abhängig macht.

our friends over at @rpgp just published a monster milestone, humbly tagged 0.16 😍 with
- streaming decryption and encryption
- post-quantum-cryptography
- API streamlining.
#rPGP is a full Rust implementation of #openpgp which counts among the fastest and most compliant implementations today, and includes security audits. Note: #deltachat uses a restricted subset of OpenPGP, and follows best practices (eg using the same ed25519 keys implementation as #signal) github.com/rpgp/rpgp/

A Pentagon-wide advisory went out one week ago warning against using the messaging app Signal, EVEN FOR UNCLASSIFIED INFORMATION.
"A vulnerability has been identified in the Signal messenger application," begins the department-wide email, dated March 18, obtained by NPR.

European #antifascist recommending to use a service running in a fascist-turning country on servers owned by a fascist-friendly billionaire? This is weird.
Focusing solely on the E2EE misses a lot of points, one of those being that with #signal the ends have to be Android or iOS ~spyphones~ smartphones, which is not really something you can have 100% trust into IMHO.
"if you need a tool to communicate privately with your friends and family–even if your chats are boring, mundane, and totally legal–#Signal is the best damn choice I can recommend."
is the conclusion after 6 parts of detailed and well explained code review that starts at soatok.blog/2025/02/18/reviewi… by @soatok

that is why I don't like people recommending moving from #WhatsApp to #Signal, better use messengers that don't depend on US servers and companies, like European messengers like #ArcaneChat
One thing I don't like about #Signal is that it only supports one mobile device per account. I know they want to make it easy for the average user. But for someone who has two phones, it's very limiting.
That's why I prefer #Matrix. Adding another device and decrypting all existing messages doesn't even feel so clunky anymore.
@hans06801
Also why there is a checkmark in "Security Audits" column for #Signal?
Did you manage to find any Signal security audit?
fosstodon.org/@link2xt/1140336…
For all other messengers listed I can easily find at least one audit report, but not for Signal.
I tried to find when #Signal has published the most recent #security audit, and it turns out they either never published an audit or their code was never audited at all.The closest thing I found is the list

If you're still recommending #Signal, you may have missed the tech oligarchs' takeover of the US government. The best time to recommend European alternatives was 8 years ago; the second best is now.
Meanwhile, over on Twitter/X, sending links to connect via #Signal are blocked and marked as malware.
I am sure this is just an unfortunate bug ;)

Happy I Love Free Software Day! 💕
Unfortunately, this year I could not join nor organize any in-person celebration, BUT of course I want to share my gratitude to the many, countless #FreeSoftware services I don’t merely use, but actually depend on.
Last year, I decided to focus only on #YunoHost, because it would have been crazy to list all the projects I use and I love.
This time, even if I will most certainly forget someone, I am challenging myself to mention all the #LibreSoftware my life is powered by.
Without further ado, THANK YOU to:
Lastly, but most importantly, the biggest thank you goes to all the free software libraries and dependencies the above mentioned #software are made of/built with, including #C, #JavaScript, #Python, #Rust, and all community-maintained programming languages.
I am super sorry if I forgot someone!

This is what I think about whenever infosec wonks on here start telling people they should use matrix or xmpp+omemo or whatnot instead of signal
To be fair, I understand the arguments and to a large extent I agree with the critiques. However, I think anyone making these recommendations is vastly underestimating the capacity or appetite for most people to deal with the user experiences presented by these alternatives.
User experience is the ultimate force multiplier. For anything that requires network effects to function (ie most anything involving communication), if it doesn't *just work* then you've lost 90% of your audience.

Journalists use #Signal to talk to sources and share tips safely. The app helps protect privacy, but #journalists are often targets. To stay safe, they should secure their Signal account. This article explains how. The tips are also useful for ordinary users.
I think I would prefer #XMPP, but according to this article, #Signal is more secure
