The well-known GNOME desktop environment is faced with trademark troubles because the Groupon firm wants to launch a proprietary product with the name GNOME and defined as "a tablet based point of sale operating system for merchants to run their entire operation", which can be easily assimilated with the actual free software GNOME desktop environment for Linux systems.
Even if you are not a GNOME or Linux user, this concerns the whole free software community, so help spread the word about this. GNOME needs support from the FLOSS community, and also money to stand juridically against a billion-dollar business.
