There's a fair amount of EA discussion of utilitarianism's problems. Here's EA founder Toby Ord on utilitarianism and why he ultimately doesn't endorse it:

>If Effective Altruists want to speed the adoption of AI with the general public, they’d do well to avoid talking about it, lest the general public make a connection between EA and AI
Very few in the EA community want to speed AI adoption. It's far more common to think that current AI companies are being reckless, and we need some sort of AI pause so we can do more research and ensure that AI systems are reliably beneficial.
>When they start talking about the utility of committing crimes or other moral wrongs because the ends justify the means, I tend to start assuming they’re bad at morality and ethics.
