But I cannot understand why they decided to roll their own license instead of going with the usual dual licensing everyone is doing. Perhaps because they wanted to enforce the "thou shalt cite me" clause? As an academic myself, I also cannot understand how they could possibly think that putting artificial barriers for the use of the software by non-academic "non-commercial" individuals could possibly be a good idea ethically. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
