Okay. So, Sugar has to be free. It has to be free software, software libre. We don't have the right word in English really, for freedom. And the reason is because Sugar is about learning. And learning fundamentally is not about receiving ideas it's about appropriating the ideas. Putting and idea to use. You can't do that unless it's free software. And there is another aspect of free software which is an aspect of culture, that is important to learning. Free software is not just about sharing, free software is also about critiquing. It's about engaging in a critical dialogue about ideas. And that's fundamental to learning. And so without the culture of free software, the learning is not as rich. So Sugar has to be free software.
