一啲批評認為，由於粵文維基百科同中文維基百科同樣用漢字寫，因此粵文維維基百並無必要存在。之但係，隨著越來越多各國家各種語言嘅維基百科嘅建立，其中包括多個漢語維基百科)，粵文維基百科嘅存在已經有咗更多可供參考嘅例子。亦有人認為[誰?所謂方言只係官方重視一種語言而輕視另一種語言嘅結果，實際上語言之間本來無所謂方言，而唔係一種方言而係一種獨立嘅語言。其他人認為[誰?使用相同嘅文字並不能否定文維基百科嘅獨立存在性，例如多種歐洲語言都使用拉丁字母，但並不妨礙佢哋成為獨立嘅語言。
One criticism suggests that since Cantonese Wikipedia and Chinese Wikipedia are also written in Chinese characters, there is no need for Cantonese Wikipedia to exist. However, with the establishment of more and more Wikipedias in various countries and languages, including several Chinese Wikipedias, there are more examples of the existence of Cantonese Wikipedia. There are also those who believe that the so-called dialect is simply the result of the official emphasis on one language and the contempt for the other, when in fact there is no dialect between languages, not one dialect but an independent language. Others argue that the use of the same script does not negate the independent existence of Wikipedia, for example, the use of the Latin alphabet in many European languages, but it does not prevent them from becoming independent languages.
