Dotnetnuke is not in "module business" but they love to acquire modules and make them unavailable for community users though. Anyway..
Which module vendor do you think DNN is going to acquire next? Of course they are not in module business and they are not making money by making these modules available only to DNN Enterprise users. They are providing these modules for free to these users and no these modules does not make the "on edge" buyers to buy the enterprise version. That would be ridiculous. That would mean DNN is in module business, which they are not as Shuan and other BODs keep telling us. They are just in acquiring business.
I would like to know so I don't buy that module and then lose it to DNN.
