Earlier quoted context omitted.
Without IP GNOME would not care. GNOME users would know not to associate Groupon with GNOME, and without IP you could call all your stuff anything you want, and that does not mean anything to anyone else, unless you manipulate people into seeing the wrong brand in the wrong place. IE, deception.
Your misunderstanding highlights why we need to demolish the term "Intellectual Property". Patents and Copyright stifle innovation and should be reformed or abolished. Trademark is essential consumer protection against fraud and manipulation and is extremely important to keep, although it needs to be fixed not to require prohibitive costs to defend one's trademark.
There was no misunderstanding. Trademarks, as you yourself have said, are also an exploitative tool of abuse by entrenched interests. Impersonation and slander should still be illegal, but the claiming of ownership of a name is only rife for abuse. I'm against IP in general.
