Thank you so much for citing checklist for me, thus saving my time:
"It is possible to omit the author in cases where no name can be seen by a regular user opening the original article in the browser." The fact that HOVERING on author images reveals their names does not mean that they REALLY can see their names.

Here is a great counter-example, where the name of a real author can be easily seen and identified without hovering:

I thus assert that your issue is invalid, and retrieving author name from og:author, as my template does, is acceptable; moreover, it is a better and much more reliable practice
