Text editors just format and display text. IDEs have compilers, debuggers, indexers, source control integration, analysis tooling, WSL integration, SSH integration, and whatever plugins you might have installed.
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.
