I need to write a far longer response to that paper, but I’ll briefly respond (and flag to @Christian Tarsney) that I think my biggest crux is that I think they picked weak objections to causal domain restriction, and that far better objections apply. Secondarily, for axiological weights, the response about egalitarian views leading to rejection of different axiological weights seems to be begging the question, and the next part ignores the fact that any acceptable response to causal domain restriction also addresses the issue of large background populations.
I think there are pretty good reasons to expect any reasonable axiology to be additive.
