Nobody asked that the service to be limited to women. That's something you're adding to the conversation. So it seems to me that you're politicizing it even more.
I am speaking of two separate things: a commercial product and a nonprofit that gives away free subscriptions to the commercial product. Although now that you mention it, if some sort of existing nonprofit focusing on diversity in tech built a service, that would also be something I'm glad to support.
One easy way to tell that I didn't want guys excluded from the service: I said I wanted to subscribe, and I am a guy.
