I know he mentions that it's for "privacy reasons"... but any rational person is going to conclude that you are not disclosing the reason because it reflects poorly on you and undermines your gripe.
Now if you are comfortable disclosing the cause, then perhaps there is some value to be gained in raising the issue. But not disclosing is a no-win situation... right or wrong you will be perceived to be in the wrong.
EDIT:
Funny that I get downvoted, yet most comments are basically "Clearly this person did something worse than they realize..."
