Beyond the obvious and almost trivial answer: because developers like and they don't care what you think about it and if you don't like, program your own editor.
I think in this site participate many package authors and developers of many of the technical jewels we get in LaTeX. And maybe more than one has to do with the development of one of the many dedicated editors that there are today, so I ask the question here.

Texmaker and its fork
