It would be great if businesses and individuals took seriously the matter raised in this post, but the irony of this statement is that it doesn't align with what you generally find on independently created-and-run websites; getting the info unadorned is usually best found the big platforms, because Facebook, etc. control the site design, and the userbase has to contend with just providing the information. And even if you find, say, the visual design of a platform's look and feel to be unappealing, it is at least uniform.

Why are these back "links" not actually HTML links? Annoying. Conjecture: Since this is what you get with creator-controlled presentation, that's one of the reasons why people opt for Twitter et al.

I don't even think that's it. Plenty of people are willing to do with poor UX. (Look at GitHub.) The overriding factor is actually a consistently familiar interface. (Look at GitHub.)
