Aaron Swartz may have left everything to Givewell. This makes it even sadder somehow in ways I can't fully describe.

The same page shows that the last Reddit comment he ever made was on /r/HPMOR. I don't think I noticed at the time - I don't think I knew he was a fan.

I have said and will say that Aaron Swartz acted heroically in trying to free the scientific literature. It was a good try.
