Paraphrasing, I believe it was said by an SIer that "if uFAI wasn't the most significant and manipulable existential risk, then the SI would be working on something else." If that's true, then shouldn't its name be more generic? Something to do with reducing existential risk...?

I think there are some significant points in favor of a generic name.

• Outsiders will more likely see your current focus (FAI) as the result of pruning causes rather than leaping toward your passion -- imagine if GiveWell were called GiveToMalariaCauses.

• By attaching yourself directly with reducing existential risk, you bring yourself status by connecting with existing high status causes such as climate change. Moreover, this creates debate with supporters of other causes connected to existential risk -- this gives you acknowledgement and visibility.

• The people you wish to convince won't be as easily mind-killed by research coming from "The Center for Reducing Existential Risk" or such.

Is it worth switching to a generic name? I'm not sure, but I believe it's worth discussing.
