I think there are a lot of people who are not comfortable with vi. Its much the same reason that some Linux distros default to nano.

I spend a fair bit of time on Linux command lines, but I use a mix of different TUI and GUI editors (including ones that work over ssh for editing files on servers), and none of those are vi. I can manage vi if I must, but its an effort and distracts from the task because I have to think about how to do things in vi.
