Despite the silliness of his argument. More collaboration on most opensource software would actually be better, but not when there is no alternative. I believe you need at least two open source alternatives, with development teams that can try different approaches, but from this there should be one collaborative project that combines the best of both. The latter should be the de-facto standard. This would be a good thing for the opensource community as it would unite instead of divide a small pool of resources. Further to the point, it would not diminish options as the truly technical savvy can install either variant, or still make their unique version of either. Creativity would still be able to thrive without needing countless options that are essential the same with a small layer of veneer.
