No promises of salvation. But plenty of room for critical questions.\n\nLinks:\n\n* https://gitlab.opencode.de/it-planungsrat/fit-ab/zapuk\n* [https://netzpolitik.org/2025/verwaltungsdigitalisierung-arbeitsgruppe-empfiehlt-matrix-protokoll-fuer-behoerdenkommunikation/](https://netzpolitik.org/2025/verwaltungsdigitalisierung-arbeitsgruppe-empfiehlt-matrix-protokoll-fuer-behoerdenkommunikation/)\n* [https://www.digdir.no/standarder/verdens-programvare-star-pa-skuldrene-til-apen-kildekode/7195](https://www.digdir.no/standarder/verdens-programvare-star-pa-skuldrene-til-apen-kildekode/7195)\n* [https://gitlab.opencode.de/fitko/matrix-g2x/](https://gitlab.opencode.de/fitko/matrix-g2x/)\n", "logo": null, "persons": [{"guid": "a0d5df64-4fa2-438e-b330-c3b1407301d8", "name": "Yan 't' Minagawa", "public_name": "Yan 't' Minagawa", "avatar": null, "biography": null, "url": "https://events.ccc.de/congress/2025/hub/user/t"}], "url": "https://events.ccc.de/congress/2025/hub/event/detail/communicate-with-governments-with-matrix-ama-about", "links": [], "do_not_record": null, "do_not_stream": null}, {"guid": "24675365-bf7c-406f-bd23-e7780d6f07ab", "code": null, "id": 246753, "date": "2025-12-29T17:00:00+01:00", "start": "17:00", "duration": "00:56", "room": "Matrix Assembly", "slug": "39c3-inofficial-sailfishos-user-meetup", "title": "Inofficial SailfishOS User Meetup", "subtitle": null, "language": "en, de", "track": null, "type": "other", "abstract": "Different SailfishOS users meeting up and chatting\r\n\r\nAnyone welcome, even people who are just interested in SailfishOS.", "description": "", "logo": null, "persons": [{"guid": "15826bdb-f6d9-4f6a-ad81-9bc4d957bc3e", "name": "deepbluev7", "public_name": "deepbluev7", "avatar": null, "biography": null, "url": "https://events.ccc.de/congress/2025/hub/user/deepbluev7"}], "url": "https://events.ccc.de/congress/2025/hub/event/detail/inofficial-sailfishos-user-meetup", "links": [], "do_not_record": null, "do_not_stream": null}, {"guid": "9b890c44-e35e-4442-bd5d-9bae517738ca", "code": null, "id": 989044, "date": "2025-12-29T23:00:00+01:00", "start": "23:00", "duration": "01:00", "room": "Matrix Assembly", "slug": "39c3-promoting-homeservers-outside-the-default-matrixor", "title": "Promoting Homeservers outside the default matrix.org", "subtitle": null, "language": "en", "track": null, "type": "other", "abstract": "Many client apps funnel their users signing up towards to matrix.org homeserver out of simplicity for the onbparding UX, meaning the decentralized public Matrix network practically has a big concentration on one server.
