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 :)
With Delta Chat Version 2, chats are end-to-end encrypted, always and by default. Previously it was possible that chats without green checkmarks could contain messages without end-to-end encryption...
I think "it would struggle to resist takedown requests" is a HUGE understatement.
In fact, I don't think they could refuse.
Given the current political climate, it's one of the main reason's I jumped-ship to Delta Chat and, to a lesser extent, Session.
Decentralisation holds the key to the future.
IMHO...
Right on ...
@delta So are there already backdoors or are you open for implementing them?
The last sentense of you is pretty sus.
I wonder if this could become an approach (in a dystopic future that hopefully never comes):
"In compliance with local laws, we were forced to add a backdoor into this source file over there, line 233-235.
As this is open source, people could obviously remove those lines before building..."
(I wonder if the Hackerparagraph also applies if the developer/company of the app points out how to 'hack' it. 
)
@delta
#DeltaChat nutzt das Email-Protokoll kann von daher als Email-Anbieter verstanden werden, auch wenn man vom Layout her damit chatten kann.
Email-Anbieter sind keine Anbieter von digitalen Diensten:
"Laut OLG ist ein E-Mail-Anbieter schon kein Anbieter von digitalen Diensten im Sinn des § 21 TDDDG. Danach sei ein digitaler Dienst als ein Dienst im Sinne des Art. 1 Abs. 1 b) der Richtlinie (EU) 2015/1535 definiert, mithin als "elektronisch erbrachte Dienstleistung". Laut OLG folgt aber aus Art. 1 Abs. 3 der Richtlinie i.V.m. Art. 2 c) der RL 2002/21/EG klar, dass TK-Dienste keine digitalen Dienste im Sinn des § 21 TDDDG sind. "
https://rsw.beck.de/aktuell/daily/meldung/detail/e-mail-anbieter-muss-keine-auskunft-ueber-nutzerdaten-geben
Von daher muß ein Email-Anbieter keine Nutzerdaten ausliefern.
So sieht es für Deutschland/EU aus.
Assuming that the English translation is correct, in summary:
@delta being based on email means that chatmail relays don’t have to provide user data, since email providers aren’t classified as digital service providers.
If this understanding is correct, then even with chat control Delta Chat has a loophole that will exempt it from the worst aspects?
Actually, they can, by just blocking nine.testrun.org, they can stop most new users.
#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" ... https://delta.chat/en/2025-06-04-surge-donations#funding-for-a-globally-scaled-chatmail-relay-network (Funding is looking good currently btw!)
Consider a stateless message queue transport layer similar to simplex.chat, automatically using multiple temporarily generated email accounts to hop between multiple servers.
Webxdc is perfect, you have the potential to become a truly open WeChat/Telegram alternative, seize it.
