@delta so yeah, #deltaChat does proper #E2EE with #SelfCustody in a #decentralozed, #SelfHosting capable fashion.

• Whilst one may argue that #IMAP & #SMTP as well as #PGP/MIME were never "designed" for that, they do work reliably, don't require much cooperation (cuz even the strictest #CGNAT allows #eMail!) and can be transparently shoved through #VPN|s & @torproject / #Tor without much fuss.

Plus the "store & forward" architecture of #eMail lends itself to #AsynchronousCommunication, making it a good option when people need to "keep it brief"...

• Add to that existing technologies like "#DataMule" style units to provide almost-#airgapped communities with "high bandwith, high lantency" connections as well as #SATCOM, I'd not be surprised if delta chat would work excellent everywhere on the planet - regardless if using #Iridum in #Antarctica, 10GBit/s FTTH in Sweden or uucp in Western Sahara.

@darkphoenix @SiteRelEnby @sekka personally I just consequently refused to use any #centralized #SingleVendor & #SingleProvider messengers, as there are already good, #decentralozed and #secure (incl. #SelfCustody of #Keys) solutions.

• Need 1:1 Chats? #XMPP+#OMEMO!
• Need public Group Chats? #IRC
• Need private Group Chats? #SelfHost #Zulip (you can even do that in a #VPN or as #OnionService!)
• Need 1:1 Videocalls? #WebCall is fine!
• Need Group Videocalls? #JitsiMeet has you covered!
• Need Group Voicechat? #Mumble just works!
• Need to exchange larger files privately? #OnionShare makes it as easy as uploading it to #oshi.at !

And yes, I have and still do use all these tools regularly!

• Espechally since it's basically illegal to get new & anonymous SIM Cards, and thus every Phone Number must bebconsidered #PII that one should not rely upon for privacy reasons...
