The one you linked to only allows binary distribution. This is how those projects support themselves, by offering tiers of pricing depending on the user needs. We just require that at least one of the licenses allows redistribution of the source. So I'm understanding that by your world-view, Open-Core projects are not open-source? or that open-source can only be used if sanctioned by the OSI? I'm afraid that no one has monopoly on that term. It means different things to different people. We call our products "Commercial open-source", which you can find the usage of which on the web and wikipedia as well. Most projects on GitHub do not have a license, which means they are copyrighted by default. We vet licensing for each project on our site, to make sure there are no copyright or licensing breaches, and provide a range of licensing options to fit the developer POV. Not sure where all the hate is coming from.
