I dislike when they say in news clips that Signal represents the “current gold standard” for E2EE chats, it doesn't, Signal is a helluva lot better than the commercial stuff that mines user data but there's stuff like SimpleX Chat that doesn't leak even metadata because it doesn't have it.
Still, this is a good thing, these megacorps have their iron grip on people because they have raised walls around their services making it painful for people to move to a different service, tearing down those walls can only help us all.
Meta says that it will only allow third-party developers to use another protocol besides Signal, “if they are able to demonstrate it offers the same security guarantees as Signal.”
If matrix finally finishes implementing MLS, maybe they could convince meta to use it.
