Yes. The trouble with “shut up and multiply” - beyond assuming that humans have a utility function at all—is assuming that utility works like conventional arithmetic and that you can in fact multiply.
There’s also measuring and shut-up-and-multiplying the wrong thing: e.g., seeing people willing to pay about the same in total to save 2000 birds or 20,000 birds and claiming this constitutes “scope insensitivity.” The error is assuming this means that people are scope-insensitive, rather than to realise that people aren’t buying saved birds at all, but are paying what they’re willing to pay for warm fuzzies in general—a constant amount.
The attraction of utilitarianism is that calculating actions would be so much simpler if utility functions existed and their output could be added with the same sort of rules as conventional arithmetic. This does not, however, constitute non-negligible evidence that any of the required assumptions hold.

It even tends to count against it, by the A+B rule. If items are selected by a high enough combined score on two criteria A and B, then among the selected items, there will tend to be a negative correlation between A and B.

I don’t know who’s making that error. Seems like scope insensitivity and purchasing of warm fuzzies are usually discussed together around here.
Anyway, if there’s an error here then it isn’t about utilitarianism vs something else, but about declared vs revealed preference. The people believe that they care about the birds. They don’t act as if they cared about the birds. For those who accept deliberative reasoning as an expression of human values it’s a failure of decision-making intuitions and it’s called scope insensitivity. For those who believe that true preference is revealed through behavior it’s a failure of reflection. None of those positions seems inconsistent with utilitarianism. In fact it might be easier to be a total utilitarian if you go all the way and conclude that humans really care only about power and sex. Just give everybody nymphomania and megalomania, prohibit birth control and watch that utility counter go. ;)
I don’t think it’s even linearly combinable. Suppose there were 4 copies of me total, pair doing some identical thing, other pair doing 2 different things. The second pair is worth more. When I see someone go linear on morals, that strikes me as evidence of poverty of moral value and/or poverty of mathematical language they have available.
Then the consequentialism. The consequences are hard to track—got to model the worlds resulting from uncertain initial state. Really really computationally expensive. Everything is going to use heuristics, even jupiter brains.

Well, “willing to pay for warm fuzzies” is a bad way to put it IMO. There’s limited amount of money available in the first place, if you care about birds rather than warm fuzzies that doesn’t make you a billionaire.

The figures people would pay to save 2000, 20,000, or 200,000 birds were $80, $78 and $88 respectively, which oughtn’t be so much that the utility of money for most WEIRD people would be significantly non-linear. (A much stronger effect IMO could be people taking—possibly subconsiously—the “2000” or the “20,000” as evidence about the total population of that bird species.)

An explanatory reply from the downvoter would be useful. I’d like to think I could learn.
