My remark was intended to cite how much farther bit keeper could have gone had it been open source from the start rather than belittle what bit keeper accomplished.<p>At work, many of my newer colleagues have backgrounds in closed source software development. We are developing software that has no exact analog to existing software, and we hope that it will have a big impact. If it becomes as important as we think it could be, then bit keeper vs git is a fantastic example of why our work should be open source from the start.
