I'm glad I've been using Bitwarden anyway, I guess, but to me, this is totally unacceptable for security-critical software. You absolutely need to make it possible to self-host. If you're content to only ever be available to low-information, low-effort individual consumers, fine, I guess that's a market, but you've locked yourself out of ever being able to sell to high-security organizations that can't use public cloud services.
