I mean, fair, but does it follow that someone who dislikes utilitarianism or feels it's disprovable must consequently dislike EA? Because that seems to be the thesis of this essay.

I guess it comes down to this: when people argue with utilitarianism, in my experience it's specifically the part about treating strangers and friends equally, i.e. the idea that it might be better to save two drowning strangers than to save one drowning friend. I don't think EA relies on that or is based on it; you can have a value system that says it's better to save your drowning friend than to save ten or a hundred drowning strangers, and still find EA valuable.
