Something smells wrong
There are a number of points in this article that put a rather off color on GitLab. The fact that they made a video about how happy people are, and some of the women mentioned are gone. The fact that a report was credited to a woman who apparently had nothing to do with it. The insistence that diversity is important and GitLab wants to promote women, but fires them as soon as they reach too high a level.
Individually, none of these points are, as of themselves, significant, but I find that the accumulation is significant.
Something is wrong at GitLab, and there appears to be a coverup in progress. Not a good sign.
