The About section of the Black Girls Code site says that its goal is to provide girls of color the opportunity to learn about technology and computer science. It doesn't say anything about level of wealth. So it is unclear to me how the name "Poor Kids Code" would be better

Judk has spoken! Change your mandate to get poor people to code and not focus on any unpleasantly ethnic segments. Since all black girls are naturally born poor, they will completely fit in with all the other poor kids. Embrace judk's non-discriminating rainbow of poverty!
