Since Matrix (and thus BundesMessenger?) currently doesn't provide standard security guarantees for its end-to-end encryption (the mitigation to the "Simple confidentiality break" from https://nebuchadnezzar-megolm.github.io/ is still in the design phase; same for the IND-CCA break, but that doesn't seem exploitable in practice) I wonder how much the German government cares about E2EE for its civil servants? The blog post mentions E2EE prominently, but any insights to share on whether that mattered for this particular adoption?
