I just cannot fathom the thinking behind presenting URLs but not linking to them. The author clearly knows something about all this (unless it's AI-written, but I don't think it is), so how have they made such a glaringly obvious mistake?

I'm half wondering if they're using a very strange CMS to publish this blog. The fact that they seemingly cannot use the correct double-quote character in their code blocks lends a bit of support to this theory.
