It's just a passive aggressive means of disagreeing with the value of something without providing any argument for such. The exact same rhetorical fallacies are widespread when it comes to debates around the values of e.g. pursuing efforts to become a multiplanetary species. I think it's safe to call it a rhetorical fallacy because its underlying premise implies humanity can somehow only focus on a very finite number of things at once and that funds directed to 'your thing' would somehow otherwise be directed to 'their thing' which is even more absurd.
