You are their friend and have met them face to face? I will provide some context about the suggestion to disable NTP. It is possible that [email protected] came from one of the following ``privacy security'' communities (most suspected first) - GrapheneOS (Hardened Android with a Hardened Linux Kernel) - Madaidan's Insecurity (https://madaidans-insecurities.github.io) - privsec.dev (Systemd Lovers and Kernel Hardener) - Secureblue (Fedora Lovers, Kernel Hardener and Chromium Hardener) - isopenbsdsecu.re (Is Open BSD Secure) - PrivacyGuides - CalyxOS - Techlore - ... The first 4 communities agreed that NTP is not secure: > The most popular time synchronisation method, NTP, is insecure, > as it is unencrypted and unauthenticated, allowing an attacker to > trivially intercept and modify requests.

Do you know that Tommy (the owner of privsec.dev, who made a long post about linux hardening, F-Droid security analysis, etc) **haven't written a single line of code**, but can still talk about encryption, security and hardening all the days?
