Ten to five years ago I was reading MSDN Magazine, and in a few articles I stumbled upon sentences like "The user should... She needs to...", with "she" referring to the user. Unfortunately I can't find anymore the original quotes, but this was the gist of them. Now, English is not my native language (French is), and I wondered then why was the author using "she" where I would have used "he" or (even then) "they".
I know there are related questions here, but I don't think mine is exactly a duplicate. What I'm really asking here is whether "she" may have been considered in the recent past a more inclusive pronoun than "he".
It seems that - at least according to SE Code of Conduct - singular "they" is nowadays an acceptable default when nothing is known about someone's gender preference. My intuition is that a few years ago using "she" may have been a - maybe American English - attempt for inclusiveness, but I'd really like to hear the opinion of native speakers on this feeling of mine.
