Sure it is. The fallacy here is focusing on the messenger: THEY do this, THEY do that, if YOU do this, if YOU do that... But the messenger is not the topic.
Instead, focus on the initial charges and whether they are factually correct. The messenger doesn't matter. They could be a total hypocrite, they could have 0 values, they could eat babies, and still be 100% right on the issue. Not to mention, other messengers say the same thing, and attacking them won't make the claims incorrect, either. This is why the phrase "don't shoot the messenger" exists.
When you use whataboutism, you behave at least as poorly as the person you claim has no values, or who you claim is a hypocrite. This is because you yourself refuse to criticize the behavior present in the initial charges. How does sinking to what you believe to be their level, help resolve the initial charges?
tl;dr: there's a reason why 'no u' is considered a joke and not a serious defense of one's behavior
