Nothing sucks the wind out of the presidential campaign announcement sails like a little copyright law dispute. As noted by Vox's Andrew Prokop and detailed by The Washington Post, Rand Paul's official announcement video was suspended thanks to YouTube's "Content ID" system. It automatically checks videos that are uploaded to the service against a backlog of copyrighted content, and alerts the rights holders when it finds an infringement. When that copyrighted material is used without permission, the companies or individuals who hold the rights can choose what happens to the offending video from a number of options, like selling ads against it, muting the audio, or — perhaps the most dastardly considering Paul's stance on the NSA — gaining access to its viewership statistics.
