Wikipedia has been criticized for its uneven accuracy and for exhibiting systemic bias, particularly gender bias against women and a left-wing political bias.^[11][12][13] In 2006, Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the "biggest and perhaps the best encyclopedia in the world", and a testament to the vision of Jimmy Wales.^[14] The project's reputation improved further in the 2010s, as it received praise for its unique structure, culture, and absence of commercial bias.^[3][11][15] In 2018, Facebook and YouTube announced that they would help users detect fake news by suggesting links to related Wikipedia articles.^[16]
