In this case it seems they fixed a factual error in attributing a statement to the wrong author, which is fair enough.
Yes, agreed SBF, but, if they made changes, it would be the honest thing to do to point them out.
For example, a NYT article I recently read about Gary Johnson and his "what is Aleppo" gaffe, said:
An earlier version of this article misidentified the de facto capital of the Islamic State. It is Raqqa, in northern Syria, not Aleppo.
An earlier version of the above correction misidentified the Syrian capital as Aleppo. It is Damascus.
