Base tech resilience comes from tools that can be used offline. #deltachat apps are offline-first in that you can create chats, send messages, look at messages/media and trigger establishung contact via qr code scans. And you can use #webxdc apps (with checklist, calendars, editors, shopping lists etc) because they not only don't require Internet but are barred from accessing it, providing privacy that doesn't require #gdpr or consent or login.
