This is charitable of cpervica and tarsnap; that said, for many people, it's probably easier and safer (and you'll receive greater legal protection, long-term) to proceed by uploading your (even pre-encrypted) documents to Google Drive or a similar cloud-based storage system.

To attempt to explain - although it could be an excuse: I interpreted this situation as one that could lead to potentially less-familiar users onboarding at a risky and dangerous point-in-time, and that that could lead to the introduction of additional hazards.
The nature of the service as a highly privacy-preserving and technical one, I feel, could mean that practice and care are required (ideally, during a less risky time) in order for users to learn the nature of the system and how to use it appropriately in their own environment(s).
