I don't really disagree much with what you said. My favored PLang Nim (https://nim-lang.org/ -- it has both `ref` and `ptr` styles of pointer, one auto-managed, one manually managed) even changed a while back it's `nim c --gc=x` command-line language to `nim c --mm=x`, and I was in favor of said change.

However, it does inspire me to write.. The kernel of all this terminology confusion is under-exposure of industrial programmers to not just academic terminology, but also the very design space you mention (which has always been nicely covered by Jones' outstanding book). Just to take an example from the root of this thread:

>widespread common usage of the term “garbage collected programming language” which specifically contrasts manual languages like C++ or Rust against garbage collected ones

Boehm-Wiser conservative collection for C, among the most manual languages of all, pre-dates its very first ANSI 1989 standard.

This underexposure itself is downstream of the kinds of oversimplifications/lies of marketing and in this particular case came from Java. The evolution I witnessed was roughly 1) linking Boehm with -lgc and deleting (or #define'ing away) all your `free()` calls is conservative - to be precise you need compiler aid and a lot of programmers are "not perfect==awful" personality types, 2) Sun Microsystems wants to leverage a lot of reliability issues with C code and become The Platform and spends gobs of money to win hearts & minds, partly succeeding, 3) part of its ad-warfare against the then WIntel hegemony and/or tutorials/introductory material for Junior Programmers (often the target of "be more reliable" material) plays fast & loose with GC terminology because marketing plays fast & loose structurally for fun but mostly profit, 4) because human language really does == language usage a la Quine, everyone in the industry re-defines what "GC" means to bind it to a programming language instead of to a specific run-time, 5) industry & academics use different language, confusion ensues and so here we are.

This is not even the 100th time that either explicit or implicit forces of marketing have achieved confusion analogously to this. If you believe most people don't need much of what they spend on then confusion is arguably intrinsic to marketing of ideas/products. The highly misleading but suggestive metaphorical language used all over "AI" in both research and in product-lines is a more current case of this, leading anyone who knows much to have to qualify "not AGI" or other such junk just to have a conversation.

So, what is my point? Basically just that the larger problem here will persist as long as there is money to be made/attention to be garnered by sowing confusion/having people talk past each other/think some product is more than it really is. I have no meta-strategy in my back pocket to block these successful confusions, but it does seem worth being aware of it.
