ProtonMail doesn't report security vulnerabilities to the users, when researchers discover them[1]. It has also publicly boasted about hacking a phishing site, when claimed the journalist's report was based on "unsubstantiated rumors"[2]. I really hope that it has nothing to do with the philosophy Mozilla embodies.

If it helps however, ProtonVPN is by the people behind ProtonMail, the security-first email provider. They started in CERN as a mission to provide email to scientists that wouldn't be subject to censorship.
Their entire business - email and VPN both - embodies the same philosophy that Mozilla does.
It's rare that I trust any company but Mozilla and ProtonMail are two of a _very_ short list.
