Sure, but I'm sure that IP laws don't demand you send CnD any fan project[1]. In the past, they were way more lenient. I guess they got scarred by their DotA experience. And honestly DotA mismanagement was their own fault.
Stuff like that has a hugely detrimental effect; see Games Workshop and Warhammer 40k fan projects.
[1] As far as I know the law doesn't prohibit to giving the server a license to run as a non-profit or giving them a cheap, short term license.
