I'm torn because as a user, the best license is a pure open source license. But I know that many companies that start out offering an open source product aren't going to be able to make that work. It's really frustrating when a product like Redis or Elasticsearch churns their license around. It would have been better for everyone if they had a clear "semi-open" license to pick in the first place, that gave them a business model while being "open enough" for my purposes. What concerns me about these semi-open licenses is, am I held hostage if the developer raises prices on me? If once I commit to the software I have no alternative to paying them for their managed service, it doesn't really help me that I have some access to the source code. A semi-open license like Llama uses is less troublesome. It isn't open source, but it's pretty clear that you just can't use it for certain activities. If I don't plan on using it for any of those activities, it's fine. I'm not committing to paying Facebook X dollars a month and if their companies struggles maybe they'll start charging me 2X or 3X or 10X dollars a month.
