As a recently graduated computer science student with deep experience working with startups, notedly with highly experienced women developers and staff within those startups, I find groups like this deeply troubling.

I believe what these groups advocate for on paper and what they knowingly actually advocate for are very different. IMO these groups foster division and group-think that makes learning harder for all involved and if anything promotes the portrayal of toxic culture as a purely gendered issue along with wrapping everything under a poorly though-out victim mentality.

Some of the best female developers I've come to know both as co-workers and mentors (although I'm a man) avoid these groups and find them counter-productive. Some have even been banned for just speaking on the issue of these groups, regarding their "real" benefit. I acknowledge there are problems with tech culture, but pro advocacy and labeling of any groups involved will never be a productive way to solve these problems.
