I think the correct interpretation of this is that OP GHW doesn’t think general community building for its cause areas is cost effective, which seems quite plausible to me. [Edit: note I'm saying community-building in general, not just the EA community specifically - so under this view, the skewing of the EA community is less relevant].
> funded by organizations/program areas that made decisions using the lens of EA
I wouldn't be surprised if a similar thing occured - those orgs/programs decide that it isn't that cost-effective to do GHW community-building. I could see it going another way, but my baseline assumption is that any sort of community-building in developed countries isn't an efficient use of money, so you need quite a strong case for increased impact for it to be worthwhile.
