I do believe that the author's heart is in the right place here, but I wonder what this is going to do to corporate adoption of PlantUML. As an individual user, I have no issue with the license. As a consultant, I am making sure my clients are aware of this very strange update. I would urge the author to please consider offering a plain OSI-approved license, at the risk of losing considerable adoption.
