Your blog says a Linux client is in progress, but Proton Drive cannot be taken seriously as a core product until it exists. Linux is a first‑class environment for many of your most technical users, and the absence of a native client is a fundamental gap.

If E2EE is the bottleneck, ship a non‑E2EE Linux client now with explicit warnings. Engineers know how to encrypt locally — Cryptomator, rclone, and similar tools already solve this. pCloud has used this model for years. Delivering a functional client early gives you performance data, crash reports, and real‑world usage patterns instead of waiting for a “perfect” release.

Proton has massive potential, but the current strategy spreads engineering effort across too many new products while the core platform still lacks critical functionality. Focus on Proton Drive first — it’s where Proton is unique, and it’s where you can actually outperform competitors.
