The right solution would be to get women interested in technology from an early age, not by raising the numbers artificially by creating a sexist scholarship.
When you want to solve a problem, is it better to wait until someone else implements what you believe to be the "right" solution (assuming you don't have the resources to do it yourself, which in this case neither etsy nor hacker school do), or is it better to simply do what you can with the resources you have to try to solve it?
