I think a lot of people have forgotten that “word processors” were originally mechanical devices, and then electrical and electronic devices, before ultimately becoming software.
Difference between Word Processor and text editor is in WYSIWYG mode of operation. At least for most of people.
Like my Sciter.Notes (https://notes.sciter.com) has better chances to be named as Word Processor as its primary mode is WYSIWYG. It also supports WordGrinder alike mode (Markdown editing) so users can chose what mode is more suitable for particular document type.
As someone who used DOS-based word processors like WordStar, and before that, a Brother word processor that looked like a typewriter with a two-line display that let you edit a whole document, funky inline formatting symbols and all, and then hit "print" when you were done, I think this statement ignores a lot of history.
