Daisy Ridley herself has come out and stated that she believes the ‘Mary Sue’ tag is sexist and inappropriate.

The odd thing is she doesn’t seem to know what Mary Sue means and she is wrong about there being a male equivalent.
An actors opinion of their character and the reviews they get is hardly the end all be all. From the article you quote is says
“The term refers to a character that has no flaws and can seemingly accomplish anything without any trouble”
Not sure what the issue is then???
