To be beginner friendly they should call it text editor. Or notepad, or quickwriter. No beginner is going to guess that something called Atto lets you write words on a computer.
"Hey, how do I insert one file into another in text editor?"
"Which text editor?"
"Text editor."
"Sounds like a personal problem."
You might object that, when it was first released, before Windows, it was not the first text editor on the operating system, which was MS-DOS, and so "Notepad" might have already been too generic even then. Microsoft would have agreed with you, because that version was called "Multi-Tool Notepad".
(And VSCode also took some really good command line name real estate)
