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 :)
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!)
