This could be viewed as shortcoming in open source licenses too. Many companies take an open core approach but license some features (maybe security related, management, scalability, etc.) with proprietary licenses and charge for them. Part of this is because traditional open source licenses tend to assume all time and resources are donated freely. It’s hard to sustain one or more people in terms of money, and some run the risk of another company reusing your source in their product. I think some viable alternate approaches to earn money through open source would go a long way towards avoiding open core approaches. But until that happens companies will do what they need to in order to keep revenue flowing.
