I know it's a microkernel which is inherently cool to me, but I don't know what else it buys you.
Can anyone here give me a high-level overview of why QNX is cool?
It's also really compact. This used to be a great selling point for underpowered car infotainment systems. Some cars had around 1Mb of RAM for their infotainment, yet they were able to run fairly complex media systems.
QNX is also used for non-UI components, just as a good realtime OS.
They were also early adopters of Eclipse, which was the "default IDE" before the advent of VS Code.
Sadly not anymore, Qnet was removed in 8.0
In general QnX was commercially mismanaged and technically excellent. I'm imagining a world where they clued in early on that an open source real time OS would have run circles around the rest of the offerings and they'd have cleaned up on commercial licensing. Since the 80's they've steadily lost mind and marketshare though I suspect they'll always be around in some form.
I've also noticed that all of the message passing system calls still accept the node ID. Are there plans to open up this interface to allow for implementation of custom network managers, maybe? I'd be very interested in exploring that.
In an era where most development-oriented software is downloaded with wget/git clone/[package manager] install, this whole process feels like a slap in the face. And don't get me wrong, this is still a huge upgrade over the InstallShield Wizard of the previous versions, which rarely worked at all, and if it did, it would butcher your /etc/profile, but its still an absolute abomination, bundling an entire JRE for the only rightful architecture x86-64 just to download and unzip a few files.

Xfce uses labwc. It works very well although standard window-management keystrokes don't work. Apart from that, which is a bit of a deal-breaker for me, it's almost indistinguishable.
The page on https://devblog.qnx.com/about/ does not show what kind of company it is, who is behind it, and where they are located. Should I expect backdoors? Is it an elaborate front by north korea? Who will be able to remotely execute code on this operating system?
It's nearly 2026 and fake job applications by nation-state threat actors are common. If a new open source project with shiny marketing pops up it would really help if there is some proof that the org behind it consists of humans living in democratic countries.
Edit: The about page links to https://qnx.software/en which only shows a black screen for me.
That said, like IBM and Microsoft, they've also been on and off over the years about whether tinkerers, desktop, and other uses are welcome. So they probably could benefit from showing that this time they're opening the ecosystem for the long haul.

I'd agree using qnx.software rather than qnx.com is kinda dumb though.
Developer: BlackBerry (formerly QNX Software Systems)
On April 9, 2010, Research In Motion (later renamed to BlackBerry Limited) announced they would acquire QNX Software Systems from Harman International Industries.Try disabling content/ad blockers.

Yes, it is. It's specifically called concern trolling: https://en.wiktionary.org/wiki/concern_troll
In this case it's because the mass-market operating systems with which QNX could compete already do the things you're “concerned” about. QNX could only be an improvement in that regard.
As someone who has not worked in automotive QNX is a totally unknown brand and based on the linked website I had trouble finding out what it actually is. Also the wikipedia source just stated RIM and might not have been updated at all. Also RIM/Blackberry is not a brand that is positively recognized.
With something like Ubuntu it was an easy, verifiable story who is behind it and what they are doing. That's what the linkd QNX page was missing, and I pointed it out because I actually tried to do the due diligence and see what company is behind it and where it is located.
