adb@k3fnb just because #DeltaChat uses the email protocol you are making some wrong assumptions that only apply to classic email, sure if you go doing activism using #gmail that is not safe, but to use Delta Chat, you don't need to provide ANY personal data / metadata and hence can't leak metadata, you can create an anonymous account for a protest and throw it away afterwards, if cops get your phone they get random contacts not phone numbers unlike in #Signal etc.
