I’m not a fan of what is happening here; however, I think people sell their plugins to firms like Awesomotive because users just don’t support individual plugin developers’ pro versions as much as they should….then get on the support forums and ask a billion questions and rate 1 star because of some silly thing. It’s worth cashing out to someone who has the weight and distribution to sell much more pro licenses given the current user-developer environment. WordPress.org’s plugin folks don’t make it any easier and seem to push hard on the make everything free philosophy.
