Laura, I see your point and I agree with you. I probably wouldn’t join such community either. My point is that this harsh culture hasn’t prevented thousands of people to join the Linux kernel development and, more importantly, stick with it. If you wouldn’t join such community somebody else will. Communities don’t need to be for ‘everybody’, they just need to be for enough people to achieve their goals. I will argue for a change in the culture of Linux kernel when the current one starts to become clearly an obstacle to developing the kernel. In other words, until it’s not visibly broken, don’t fix it.
