Interestingly, whataboutism is specifically about cases of hypocrisy. The point is that the presence of that hypocrisy is irrelevant.

"It represents a case of tu quoque (appeal to hypocrisy), a logical fallacy that attempts to discredit the opponent's position by asserting the opponent's failure to act consistently in accordance with that position, without directly refuting or disproving the opponent's initial argument." -Wikipedia
