As a non-native English speaker, I appreciate pedantic editors like this one a lot. When I read Wikipedia, I want the text to be easy to understand and consistent with the rest of Wikipedia and when I edit, I want people to improve what I wrote. I wish everything I wrote had a copy-editor as pedantic as Wikipedia power users.
Some people are complaining about overly zealous editors who delete a lot of and as an Inclusionist [1] I understand the sentiment. I think deleting information from Wikipedia is pretty bad. But being pedantic about English is not deleting information, it's improving the transmission of information.
