I'm feeling a bit sad this morning with the fork of Activiti by Camunda. As you all know Camunda has been a community member of the Activiti project almost since the beginning and they made quite a number of good contributions over the years.
There are a couple of reasons that make me sad, one is that we didn't have any discussions recently and we didn't have any argument with each other. So we were very surprised when a couple of weeks ago we did a Skype call to hear that they decided to leave the Activiti community and start their own open source project (which is basically Activiti).
The second reason is from an open source standpoint, what's the gain to get here? The additional application server components would have fitted with the Activiti project also very well. So now we have two projects with the same codebase, which have to be maintained and futher developed. So twice the work without any real benefit for the open source BPM community.
The third and last reason is on a personal level. The Camunda developers are great people to work with and to have in the Activiti community. And it's sad to see them leaving for reasons I don't know or understand.
