Comparing levels of horror, yes, but to be a whataboutism you have to ask the question "why are they comparing it". They want to bring attention somewhere else. Either away from the fact that they don't have feelings about it even though other people do, or to bring attention towards something else that they're passionate about. The latter is what prompts me to label it as whataboutism. Their profile is a mix of tech and politics so there's precedent for their comment.

Why else would they bother commenting here if not to draw attention to something political? It's like going to a funeral and saying "I don't know, sure it's sad but since I'm aware of the genocide going on, it's not that sad".
