I hate reddit just as much as the rest of you... I probably hate politicians and the way this sham of a government is run even more than most of you as well.
But give the film a chance. For those of you who can't, here's a TL;DR greentext version
The important bits:
>he left reddit extremely early on because the startup culture was too much: not enough work getting done, people trying to get employees to test new gayems on new vidya consoles all the time
>spearheaded the movement to stop SOPA; if which passed you would not be seeing the film today simply because of archaic copyright laws
and before that
>wrote/hosted a site that was a direct predecessor to Wikipedia "for fun" as a school project
>wrote code that made RSS what it is today when he was 13
>helped to write infrastructure for creative commons, something that anyone who creates content, be it shitty deviant art or making gifs/webms of copyrighted material can legally use and share thanks to his work on the project
>downloaded an entire university's law library to analyze whether corporations who funded studies that went into books that would make said corporations look good in court and found that there was an increasing correlation of corporate sided wins in legal battles due to said funding of studies; the findings were never officially published however
relating to that last bit, something similar happened that drove him to "suicide" (of which people still speculate whether or not it was suicide or staged to look like suicide, the whole Illuminati theories start getting heavy here)
more in the second post; yes it's a two parter but it's better than watching an hour + long movie about the guy
