IRLP and the GPL

ÒI had released code under the GPL, and it led to nothing but 1000's of emails criticising my code, asking for features, wondering why I built this that way, etc... I got tired of answering questions.Ó
 
ÒThere is a strong commercial potential for this product, and I did not want to hand several 1000 hours worth of code to the private sector just to be replicated.Ó

ÒClosed code maintains a standard, which open releases would compromise.Ó
