It is good because it may finally get German healthcare systems to stop relying on fax. It’s still very different from WhatsApp or Zoom, because as I understand it won’t just be one huge central Matrix Server but rather an internal federation between various providers and maybe even servers self hosted by the hospitals. It’s similar to the French administration or the German Army having their internal federations (I think the French actually have a public instance so citizens can contact them). Why should your internal comms be federated to the public? That’s an unnecessary security risk
