If they cared so much about it as an IP, why didn't they buy it themselves? They already admitted they've had 7 years to do it. Besides (and please, correct me if I'm wrong here) Valve have a history of *purchasing* mods and bettering them. Left4Dead also started as a mod and has now become an extremely valuable license to them.
How can you deny someone the right to register a trademark you don't own yourself?
If you claim ownership of everything "by extension", where does it end?
