"By definition" proceeds to define the word in a way that most people won't agree with. Okay mate. Your definition is ass. The person that wrote the article doesn't agree with you, I don't agree with you. I will still use the word refactor when I talk about simplifying the application such that code becomes simpler through simplifying and improving the design.

I think it’s widely accepted that refactors should not change behavior. That’s my experience, at least.

Huh, I guess that's true, even on wikipedia. I will have to stop using the word then. Though I'm pretty sure most people use it in day-to-day with much more abandon.

That's the definition most people use.
