Depends on what he is going to actually do about it.
If he is addressing the issue, or is planning to, then a statement that largely defends their practices, but acknowledges room for improvement, would have been appropriate. One that says "We do a heckuva job, but we see a chink in the armor here and there and we're going to fix it".
If he is not going to do anything about it, he shouldn't have said anything. Just ignore the article the same way they ignore just about every other news article written.
