This has also happened with the language Lojban[1], which was 'forked' from Loglan[2] when the creator starting making copyright complaints so the community could maintain control.
Such an odd concept that someone could 'own' a language, but I guess if you created it I can see why you would want to.
I think it's a great lesson for any creator. Just because you have invented something does not necessarily mean you have the right or are capable of dictating how people use it.
I seem to remember Umberto Eco mentioning that he does not offer his own interpretations of his novels for a similar reason, but I can't find the quote.
