In October of 2012, the Library of Congress elected not to renew DMCA exemptions that explicitly allow end users to unlock their cell phones at will, thus ending a six year tradition. This has made a lot of people very angry and has been widely regarded as a bad move. The quest to do something about it began almost immediately. And by "almost immediately" I mean "nearly three months later and at almost the very last minute."
Still, regardless of when the outrage gained steam, the fact is it did. Quite a bit of steam, in fact. Despite the White House raising the bar for online petitions to 100,000 signatures (after the previous bar of 25,000 resulted in an entertaining, if frivolous response about why the President won't build a Death Star), you did it!
