As a Catholic, the part discussing Mary's role in the story is quite at odds with what I read, both from medieval times and more modern.

I wonder if the perspective in the article comes more from a Protestant understanding of Mary?

In Catholic teaching at least, Mary's "fiat" ("Yes") was one of the most pivotal moments in salvation history, and Mary is regarded as the "Queen" of all saints, for her role and her personal decision to say yes.
