Some reasons I might not do so:
The URL is probably uninteresting to most users. Often a link is integrated into a sentence and a URL doesn't integrate well.1
These days, with fancy search bars and whatnot, a site title is usually as reliable a way to find it as typing an exact URL. If I did supply a URL, it would be chopped to the bare minimum of
example.com
, since that gets them wherehttps://www.example.com
does anyway (with modern HTTPS redirection), with a lot less typing.While it might seem more transparent, it opens the door to worse abuses since you can put any URL as the text pointing to any other URL. The illusion of security is even worse than the knowledge of insecurity.
Since the URL is available to a savvy user in the status bar, the text is a way to add more information about it for free. If it were a link for
josephextraordinarilylongname.example
my anchor text could be "Visit the creator's website" and some users would be able to glean that Joseph Extraordinarilylongname is the creator.
Some reasons I might do so:
As the recommendation you cited says, if you're saying something about the URL itself and not the website, you would want to show the URL. For example, "We have moved to
newsite.example
!"Similarly, to talk about a site as a domain. This might seem a little constructed, but suppose I said, "I run three websites. On
myfirstwebsite.example
, you'll find... On my secondwebsitemysecondwebsite.example
,..." This would be analogous to a YouTube creator spelling out their different channel names instead of just saying "Subscribe!"In lists of resources, sometimes it's handy to have a unique identifier. Yesterday I was searching up cottage rentals. All the cottage rental sites have nearly identical names. So an aggregate site, rather than saying "Visit Cottage Rentals Canada, Rent Cottages Canada, Rentals Canada for Cottages", etc, might list URLs so I can tell them apart.
1 That said, I do hate over-integration, where articles on content churn sites will turn every last phrase into a link to something you could never guess from the anchor text...
