- Governments and organizations are questioning dependence on foreign-controlled software due to risks from automatic updates, prompting a move to Linux for reduced dependency.
- The author felt exposed without a network monitoring tool like Little Snitch on Linux, leading to the development of a Linux version using eBPF for traffic interception, Rust for the main code, and a web-based UI for remote monitoring.
- Ubuntu sends fewer system connections (9 over a week) compared to macOS (over 100), but still includes metrics to Canonical, though users can choose different distributions or maintain their own to control trust.
- Apps like Firefox can connect to tracking servers even when unused; disabling settings helps, but some connections persist. News sites may use 50-100 trackers, while LibreOffice made no network connections in testing.
- Little Snitch for Linux is a functional first version focused on privacy, not security, with open-source kernel and UI components, but a closed-source backend. It's compatible with newer kernels (6.12+) and is free to use.
