Wikipedia is definitely used in politicized way by the editors. A clear example of my knowledge is how the referendum celebrated in Catalunya (Spain) in 2017 is described in the Catalan and Spanish versions, for some topics they seem to be talking about different events. Anyone can use an english translator and check it out. Just in the first three lines the Spanish version uses the word "ilegal" and the Catalan does not, it might seem subtle but this subtlety has had huge implications in Spnish politics: https://ca.wikipedia.org/wiki/Refer%C3%A8ndum_sobre_la_independ%C3%A8ncia_de_Catalunya_de_2017 https://ca.wikipedia.org/wiki/Refer%C3%A8ndum_sobre_la_indep... https://es.wikipedia.org/wiki/Refer%C3%A9ndum_de_independencia_de_Catalu%C3%B1a_de_2017 https://es.wikipedia.org/wiki/Refer%C3%A9ndum_de_independenc...
