Why not give the new feature to paying licencees immediately and to open source 12-24 months later. A company which is building a valuable product will not think twice whether to wait for 2 years and their rivals being faster or buying a commercial license. And everyone else just has to wait, they will get it for free one day, ignore their hate. I have seen systems too where every new feature to an open source project had to be sponsored by big companies. If nobody is paying for it, it will never happen.
