When distributing modified GPL-licensed binaries, you must provide the corresponding source code (or a written offer to provide it) under the same license. Providing a downloadable source tarball and/or a written offer URL for at least 3 years is recommended. Failure to comply has real legal consequences (cases exist where companies were fined). :contentReference[oaicite:25]{index=25}
Derivatives must avoid confusing use of upstream trademarks. Replace all upstream artwork/branding in core packages (base-files, desktop-base, grub themes, installer artwork). Use dpkg origins to declare CAMZUN as the vendor. :contentReference[oaicite:26]{index=26}
GNOME Foundation enforces trademark usage; do not use GNOME logos or imply endorsement. Removing GNOME branding or building forks for branding-sensitive components is the defensible approach. :contentReference[oaicite:27]{index=27}
