There is history here and Sabine is being particularly dishonest saying that professional physicists failed to engage with Weinstein. Tim Nguyen specifically along with a couple of others made a detailed analysis of the paper [1] and responded very thoughtfully. He got involved because his research area touches on gauge theory (which is the source for some of Weinstein’s Geometric Unity thing).
But that's the issue, Nguyen is not the institution as a whole so then their concerns are just talking past each other. (And perhaps typical of a professional physicists Nguyen's complaints miss this point.)
Here’s a page giving some of his side of the picture and he includes the original Weinstein paper etc if you want to read it https://timothynguyen.org/geometric-unity/
