I think that you are looking at it from the wrong perspective. 1. IDEs that are made primarily for your host operating system by who writes the operating system is basically a loss leader and is there to tie you to the host os 2. Emacs / vi / vim (full disclosure I am an Emacs user) are generally usable out of the box with no modification. Tinkering with your configuration for Emacs is for people who are experienced with Emacs and I primarily do it to make the text editor I want. 3. The actual paid solutions seem to be profitable enough for people to use but for reasons 1 and 2 will have a disadvantage to compete with them.
