I never met Aaron Swartz, but he was my brother, although much younger than me.
I cannot interpret his suicide. Suicide is never the effect of a single cause, and it is always impossible to “explain” death.
Nevertheless.
Nevertheless I know something about the causes that pushed Aaron to do what he did.
He was a computer programmer, creator and developer of the web feed format RSS, and a writer, an activist and also a Harvard researcher. Recently he played a prominent role in the SOPA campaign (Stop online piracy act) which had a successful outcome.
Aaron was known – by his friends and by FBI as well - for a history of downloading massive data sets, both to use in research and to release public domain documents from behind paywalls.
In 2008, Swartz downloaded, and released, approximately 20% of the Public Access to Court Electronic Records (PACER) database of United States federal court documents managed by the Administrative Office of the United States Courts.
According to federal authorities, over the course of a few weeks in late 2010 and early 2011 Swartz, having a JSTOR personal account as a research fellow at Harvard University, downloaded a large number of academic journal articles via JSTOR.
