Code refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior.

The fact that the maximum tweet length doubled means that Twitter's external behavior did change

I think that's the parent's point: it's not "refactoring" if the external behavior changed. Though I generally agree with the down-voting of the comment as needlessly pedantic, given the common usage of the term.

The common incorrect usage of the term is just one of my pet peeves. I couldn't help myself.

Sometimes, you may have to refactor existing code to be able to add new features.
