So many wrong things in just the title.

1. We do not use the term statistically significant because it is misleading. But the article does not make even a case for statistics and they use the term as a figure of speech.

2. The premise of the article is that the Outreachy program may not bring diversity to Debian as fast as the author desires, so they postulate tha the CoC does not have an impact. Inconsequential.
