I wonder if you and others are using the word ‘retraction’ differently than I am used to. ‘Retraction’ is very different from ‘correction’. When a scientific paper is retracted, it is disclaimed by its authors and/or by the journal, and is effectively removed from the scientific literature. The evidence that the article existed, and the fact that it was retracted, are left as important components of that literature. When a paper is corrected, this is also indicated clearly in the literature, but the paper is not removed and it remains a part of the literature.
I didn’t see any retractions, but I may have missed something. Instead, I saw corrections. For example, I noticed that people are correctly disclaiming references to the nylonase literature, because there are errors in that literature, but this is not retraction, and not even close to it.
I can easily envision a situation in which it would be appropriate or necessary to retract an entire article from the BioLogos site, and I would applaud both that action and transparency about it. But I don’t think that has happened here (nor does it seem to have been necessary), and I personally find the use of the word ‘retraction’, and especially the phrase “dramatic round of retractions,” to be inappropriate.
