Interesting article, thanks for sharing. It seems Gingerich mainly focuses on how a shift occurs -- he makes a strong critique of the supposed crisis in Ptolemic astronomy that was the precursor to Copernicus and instead argues for that broader sociocultural developments enabled the change in cosmological perspective.

For me, the concept of paradigms themselves was the most fundamental part of the book. Gingerich doesn't seem to take issue with this, at least not in this article.
