Most popular text editors blurs the line these days. Vim can be the most straightforward text editor out there, or the most comprehensive IDE depending on how much you go into its environment. I keep Vs code bare bones and mostly use it as a text editor, but it only needs a dozen extensions to be a full fledged IDE.
It's not surprising to hear few true text editors because a text editor is more or less a solved problem. Notepad++ is 20 years old and still functions fine for those who want a pure text editor. Anyone making a modern text editor is either doing it to learn or to build up into an IDE later.
