Nice. The 6.2.1 version was open and installable. This is live CD only.

QNX was closed source, then free personal version (QNX era), then closed source, then open source (Harmon era), then closed source (RIM). During the more open eras there were third-party ports of most of the Gnu tools, along with Firefox and Thunderbird. All these license changes in the 2000s killed off third party development and the point of sale industry.

I never got that. Even if just releasing it, not even open source, but for free, unsupported, they would get free software ports, exposure to potential commercial developers, and it doesn't really cost anything.
