All communication assumes prerequisite knowledge, if nothing more than that the listener or reader can hear or see and understands language at all. The top post on page one right now is "Fable turned reMarkable into Tom Riddle's diary from Harry Potter." I can't see that a single person complained, including me, that we're simply assumed to know what Fable, reMarkable, and Tom Riddle's diary are. Of those three, I only know Fable. Expanding an acronym or initialism will probably result in more people understanding the meaning but that seems far less true of software tech specifications than common public language. Non-techies probably aren't going to know what hypertext is or the difference between a markup language and any other language and may very well recognize http and html better than their expansions.
