There now is a recording of the ad-hoc #datenspuren "usable end-to-end" talk from friday evening, german audio only
Usable end-to-end security with Delta Chat and Chatmail
Over the years, Delta Chat has matured to be an easy-to-use, secure, and even fast decentralized FOSS messenger app. Over the years, Del...
The problem with #chatcontrol is deep and extremely significant. It would be a paradigm shift that implies state and corporate control of app developers and users, i.e. what you can install on "your" devices. It would empower Google, Apple and Microsoft to increase enclosure even more. Just as with the p2p wealth of good tools two decades ago, e2e tooling would remain available only to small specialist circles. Given authoritarian threats everywhere, #chatcontrol is an exceptionally bad idea.
What if a state tries to mandate us as #deltachat app devs/distributors to shut down a chat profile? Nothing. It can't be done. We have no list of chat identities, have no handle or data about them, and don't mediate the message transfer. However, EU #Chatcontrol politicians and Russian authorities would want us to insert backdoors into our FOSS code. But that is nothing than can happen overnight, and we are fine with friendly forks already. Resilient private internet communication ftw :)
Woah! Only now did we discover a great blog post from @npub12hxm...n282 who discusses the progression from hosting a #Matrix , a #Snikket and a #SimpleX server, to now running a #chatmail relay
Self Hosted Chatmail Relay for Delta Chat

 It's an excellent read, with lots of good advise, including having a public "hello" profile and another unpublished chat profile for private chatting. #deltachat apps have pervasive multi-profile support (and multi-device support) so it's pretty easy to establish such a two-profile setup.
#deltachat is being used in virtually all world regions where one or more other messengers fail to work. We recently released a major milestone (V2 security hardening releases) that prepared the ground for chat profiles to have multiple #chatmail relays at once ... failure or blocking of a single relay would not disrupt chatting anymore. But multi transport also helps with the "centralization problem in decentralized systems" ...
Delta Chat: A big user surge and funding for decentralized scale
Beginning June we witnessed a sudden surge of Delta Chat usage especially in the US and Cuba. We don’t know the social dynamics behind it but it ...
 (Funding is looking good currently btw!)
Sometimes we are surprised ourselves how well everything works :) - cross-platform #deltachat releases every 2-3 months, with a focus on never breaking the world despite significant underlying changes - many #chatmail relays humming along, including the default onboarding one serving 230K monthly users with ~0 admin hours needed -lively and sometimes controversial discussions among the diverse dozen core contributors, with an evolving shared vision, both short and long term Toi Toi Toi
#Whatsapp on #iOS had a severe 0day that was exploited in the wild for some months, and is fixed with august 20th releases

 Last year #signal also had its multi-device functionality exploited in the wild.

Hackers Exploit Signal's Linked Devices Feature to Hijack Accounts via Malicious QR Codes
Russian threat actors exploit Signal’s linked devices feature using malicious QR codes to gain persistent access to victims' accounts, Google warns.
 FWIW #deltachat has a dumber multi-device sync model, no device linking, depends on being in the same WiFI for setup (therefore no easy remote exploits), and #OpenPGP signatures and verification for ongoing usage (like all other E2EE messages).
While most of the feedback on the #deltachat V2 releases has been positive, some users sense a de-prioritization of "classic unencrypted email" usage. Indeed the current dozen or so contributors aim to evolve an exceptionally resilient and versatile private messenger app suite, with end-to-end encryption the primary focus and design foundation. However, we would support friendly forkers to develop a classic e-mail focused app suite -- say "deltamail" (work title). What do you think?
As with the demise of windows10, various meta happenings around Whatsapp open possibilities to welcome refugees. Instead of blaming them for not having had whatever insights earlier, there are often just very practical questions where a helping hand does wonders. Offering help instead of trying to convince. Currently many companies are giving win11-incompatible laptops away, often powerful systems that deserve upgrading to Linux, and then donating then. It also helps to counter hardware waste.
What are the main obstacles for you to adopt usage of #deltachat apps with your families, friends or communities? if you have other issues than the poll options please add to the replies. Oh, and those who are also living through heat waves: stay hydrated, and remind everyone else :)
