Legality: Chromium OS is open-source (BSD license). Distributing builds is legal. However, Google’s proprietary components (like some media codecs and the official Play Store framework) are not included. The Rammus Special build attempts to patch in open-source equivalents, but it exists in a gray area. You are not breaking any laws by installing it on your own hardware.
Safety: ArnoldTheBat’s builds are trusted in the Chromium OS community for over a decade.
