But are there devs for the acquired platform now?
The article says ThreadX used to be what Intel Management Engine ME ran on? How do I configure the ME / AMT VNC auth in there?

"currently running on over 12 billion devices around the world"
Is this like another baseband processor?
Everything from your x64 CPU to microSD to credit cards(not the readers; readers run antiquated Android and soon known-bad Chromium) runs some form of weird slow proprietary RTOS. It is what it is. I bet it takes ~century with help of superhuman AI to make those run an open and verified code. The situation is improving too, slowly, because using buggy proprietary code is not a goal, but means.
It's ok to be disgusted about the status quo, but that is not necessarily worth your time; IIRC one of original complaints by RMS on the state of software freedom that lead to Free Software Movement was about some HP printer running buggy custom OS. Even the point people said enough is enough goes back that far.
> weird slow proprietary
They're often not weird, a simple single task runner with a few libraries to handle common tasks and cryptographic operations. Very simple, lightweight, and they generally share a common high level architecture (there's not much variation in an RTOS)
They're often not slow, they're minimalist OSes - barely qualifying as an OS if at all - designed to run a single task, with time guarantees, and to get out of the way. In fact, if it's a single task you need to run, they're faster than any general purpose OS - by design!
They're often not proprietary - a handful of RTOS with huge market penetration used in billions of devices (and now ThreadX) - are open source and have permissive licenses. What IS often proprietary about them are BSPs, but that's a whole separate issue. Yes, there are a lot of proprietary ones out there, but as a blanket statement, it's simply not true.
> readers run antiquated Android
Many use a stripped down version of AOSP, which has become a de facto standard BSP, yes. But many, many others do not (usually a flavor of embedded linux, or an RTOS).
> about some HP printer running buggy custom OS
It was a Xerox printer, and it was because he was frustrated from adding existing job management and notification features he had written to the new printer.

"Eric Raymond claimed that Linus hasn't actually written Linux from scratch, but rather reused source code of MINIX itself to have working codebase. As the development progressed, MINIX code was gradually phased out completely."
quoting "The Cathedral and the Bazaar"

for this statement. On p. 24 you can read:
"Linus Torvalds (http://www.tuxedo.org/˜esr/faqs/linus), for example, didn’t actually try to write Linux from scratch. Instead, he started by reusing code and ideas from Minix, a tiny Unix-like operating system for PC clones. Eventually all the Minix code went away or was completely rewritten—but while it was there, it provided scaffolding for the infant that would eventually become Linux."
The only thing Linus 'copied' (rather, modelled) was the initial directory tree layout and some of the names of the core module filenames - none of the code.
Linus was interested in MINIX, no question - and motivated to write his own kernel - but he literally did not fork MINIX.
In "History of Linux" this falsehood is addressed - and it has to be said is amazing that you are parroting even still today:
https://en.wikipedia.org/wiki/History_of_Linux
I challenge you to find the code, from MINIX, that Linus copied and then modified and called it Linux. This is what forking means.
That is not true and never was.
It was in part bootstrapped on Minix but it contains no Minix code at all and was built with GNU tools.
That the MINIX code was replaced before release does not make it not a fork.
Fork: take the existing code, make your own version and start modifying. That does not apply here.
Torvalds did not take any Minix code; one of the reasons he did his own was that the licence agreement on Minix prevented distribution of modified versions. At the time Freax/Linux got started, people were distributing patch sets to Minix to add 286 memory management, 386 handling and so on, because they could not distribute modified versions.
The Linux kernel started out as 100% new original code. I was there; I watched the mailing lists and the USEnet posts as it happened. It's the year I started paying for my own personal online account and email, after 4Y in the industry.
The origins of Torvalds' kernel were as a homegrown terminal emulator. He wanted it to be able to do downloads in the background while he worked in a different terminal session. This required timeslicing. He tried and found it was complicated, so he started implementing a very simple little program that time-sliced between 2 tasks, one printing "AAAAAA..." to the console and the other printing "BBBBB..."
This is all documented history, which it seems you have not read.
You are wrong.
Furthermore:
> including the regression to a macrokernel.
This indicates that you are not aware of the differences between Minix 1, 2 and 3.
Minix 3 (2005) is a microkernel.
Minix 1 (1987) was not and does not support an MMU. It runs on the 8086 and 68000 among other things.
Linux (1991) was originally a native 80386 OS, the first x86-32 device and a chip that was not yet on sale the year that Minix 1 was first published.
Summary:
Linux is not a fork of Minix and is unrelated to Minix code.
