Meta: my answer here is probably also a good example of motivated reasoning because I likely read a bit more into what the author wrote than is factually in the blog post. Oh boy.
I think my critique is somewhat correct in that you seem to suggest that this change was made to allow for expanding the permissions from one product to all products, which I don't think one can derive from the things we know.
I think I was somewhat wrong in that I may have suggested that you said this was the only reason (which you didn't explicitly) and also in that I dismissed that they factually can use these permissions from other products now, i.e., no matter whether it was intended or not, the permissions set for other products is broader now.
Do you mind pointing out where you think this applies?
