There’s an even better alternative on the CCC’s website, the original source of the video ;)

This has likely happened because the german government created the social.bund.de instance earlier this year

The instance is almost 3.5 years old btw, which you can easily see from the instance admin account @[email protected]. It just wasn’t used by many government departments at the time, mostly the data protection agency and the BSI. The @[email protected] account itself is pretty old too. It dates back to before the whole Twitter debacle. I guess that’s also part of the reason why they decided to go full Mastodon, since they already have a lot of experiences with it.

I knew it! Hans did 9/11

Matrix is also decentralized/federated, has encryption integrated into the protocol and enjoys a broad adoption and public support. It also has pretty good integration of bots and even other message protocol services like IRC via “bridges”. The chat clients are pretty good too; Element is pretty much available for every platform but there’s other one’s which are more focussed on Desktop or mobile usage, depending on how you primarily use it.
