Well it's kinda whataboutism, but I made a similar comment on a video about an environmental crime (a copper mine had dumped an entire lake's worth of toxic sludge into a valley).

The author of the mini documentary said something about how deeply disturbed he was and how he really thought humans were better than this.

I thought that was kind of funny since, yeah the sludge lake is nasty as hell (and if the dam holding it back breaks, it's not gonna be good), but I had to think, maybe he should visit a factory farm for his next video.

That's a far worse horror, and regular folks contribute to it every day without thinking. (I forget the exact number, but something like 80+ billion animals live through that every year.) So I think it should get a little more attention.

(Not vegan, just think we shouldn't be awful towards animals.)

The issue associated with whataboutism is that it is a deflection strategy. It aims to steer the focus away from the issue at hand. Commonly regarded as intentional manipulation or lack of adherence to social conversation norms.
