Except that by saying that it's a "one woman show", they are giving her all the credit for the site, and that's what a fluent English speaker will understand. It's not The Chronicle's fault that she misinterpreted the article.

Translators move things into idiom all the time; "one-man show" (gender is easily swappable) is an idiom that comes from stage, refers to single-actor plays where one person plays multiple roles, and comes with connotations of skill versatility and industriousness.

I read her lament, but it seems to be based on a lack of understanding of the idiom. In English, the phrase "one-person show" implies nothing other than the efforts of a single person to produce something great. There is no denigration nor implication of anything else in the idiom.
