alt Hacker NewsQNX is squeezed from above by Linux, especially as real time patches have finally been fully accepted. And from below by FreeRTOS and Zephyr. Current attempt to open source is a desperate move by QNX as their market share is disappearing. Why would anyone in their right mind step on the same landmine, called QNX, which already pulled a rug from under the developers feet once? Absolutely no trust in QNX ecosystem. Save yourself pain and aggregation. Don’t use QNX.

Are you sure they want to open source it? Is this just an assumption, or can you provide a reference?
I actually tried to find out whether the source code of the kernel etc. is included in the free version they provide, but they require to install a license manager on my machine, so I stopped; and it doesn't look as if it was open-source when there is a license manager (would be very easy to get around).
There are not any real time patches for Linux: there's only the low-latency kernel. Low-latency and realtime are different things. A lot of the time the two can appear superficially similar, until they don't and your airplane falls out of they sky.
The realtime executives are not operating systems. Executives and operating systems are two different things.
QNX is a realtime operating system. It addresses the niche of a realtime operating system that isn't being met by anything else out there, and has been doing so for 40 years, even if free versions for hobbyists haven't been available for many of those years. It's not about market share since that's always been there. It's about mindshare and given the comments here, that's obviously missing.
