Swartz did not kill himself.

In a keynote speech on May 21st, 2012, Aaron discusses his involvement in bringing down SOPA to fight internet censorship, which ended with this warning:

“It will happen again. Sure, it will have yet another name, and maybe a different excuse, and probably do its damage in a different way. But make no mistake: the enemies of the freedom to connect have not disappeared.”“It will happen again. Sure, it will have yet another name, and maybe a different excuse, and probably do its damage in a different way. But make no mistake: the enemies of the freedom to connect have not disappeared.”

Only 8 months later on January 11th, 2013, Swartz committed "suicide" in his apartment.
