Dropbox vs Proton Drive
Zero-knowledge storage inside a Swiss privacy ecosystem (Mail, VPN, Calendar).
Why it beats Dropbox. Audited, open-source, zero-knowledge, and Swiss — it inverts every structural Dropbox concern (provider-held keys, U.S. jurisdiction, closed source, opaque audits) and lets you verify the claims rather than trust them.
