Did you watched the video?
Basically every some EU countries started at some point building their own instant Messenger.
- Germany has the Bundesmessenger, the BwMessenger (for the armed forces) and the TI-Messenger (TIM) for the healthcare sector
- Luxembourg has Luxchat4Gov and Luxchat
- France has the Tchap
- Belgium has BEAM
- Poland also has plans to do something
- Sweden mandated the use of open and federated chat protocols. (Via the eSam framework)
Basically all of them are based on Matrix.
Would be interesting how these apps can be used by individuals and how the interoperability works, between the different services. While I understand that some of this services are not meant for this, it would be nice to have sort of European framework in place to also replace features like WhatsApp Business and WhatsApp in general.
Frances Tchap and Germanys BwMessenger. block external federation for example.
