He said that supporting a tuberculosis charity is better than donating to SIAI, not that supporting a tuberculosis charity is the best way to fight existential risk.

I hesitate to point to language from an earlier version of the post, since multifoliaterose has taken out this language, but given that EY was responding to the earlier version, it seems fair. The original post included the following language:

I believe that at present GiveWell's top ranked charities VillageReach and StopTB are better choices than SIAI, even for donors like utilitymonster who take astronomical waste seriously and believe in the ideas expressed in the cluster of blog posts linked under Shut Up and multiply.

(emphasis added)

I believe there originally may have been some links there, but I don't have them anymore. Nonetheless, if I correctly understand the references to utilitymonster, astronomical waste, and Shut Up and multiply, I do think that that multifoliaterose was arguing that even the sorts of donors most interested in minimizing existential risk should still give to those other charities. Does that reading seem wrong?
