When I first saw this I mistook Calibri for Cambria. Why were they using Calibri (a sans serif font) at 15px for documents in the first place?
Associating the change with DEI is absolutely ridiculous, but Calibri was a silly choice. I think they should make everyone use LaTeX personally ๐

Why would anyone think this is a good thing? You're actively telling the world that your product is likely full of bugs and hard to maintain.
