Criticism
Copyright system
YouTube has often been criticized due to its copyright system. In 2012, Viacom sued Google due to how much of their content was on YouTube. In response to this, YouTube added a content ID system. Which automatically removes videos that uses copyrighted content. When it was first introduced, many videos were removed for no reason. In 2015, YouTube added a Fair Use protection system. It was criticized for it only providing protection by allowing the video to stay up to only be viewable in America. In May 2016, YouTube changed how the claim system works.
