Real talk, I think a lot of people, author included, are pretty detached about the stated age of fictional characters. Probably even more so if they grew up with those characters (and their "rule 34" counterparts), which the author may have (I'm not certain how old she is actually, younger than me certainly). It probably warrants some introspection, the article itself was not very good and it makes the graphic iconography -which she had in other articles in that series- a problem. She probably didn't think twice about it. Maybe she and the editor should have.
