It may be a licensing issue as well. Back a few years when I was evaluating it, it appeared that the three basic pieces were licensed goods:
1) The RTOS (RMX (16-BIT), InTime (32-bit) came from Radisys
2) "Flowchart Programming" license from (I don't recall, but it's patented)
3) The MMI (FIX) came from Intellution
The names of the owners may have changed (been bought) since then.
How much of this technology they now own outright, I couldn't say.
Much of their value added is in drivers for all the I/O and packaging and support. They brought the pieces together.
Some Of my experiences (as memory serves):
When I had issues with the MMI, some things were Out Of Their Hands.
When I thought a non-realtime flowchart processor (or compiler) might be nice (to create a general purpose flowchart programming system for non-programmers) I don't think they were allowed to do that, even if they wanted to.
When I wanted a scaled down runtime without MMI, this was not possible. (It is now)
Things have changed since and they (Steeplechase) were worth a look back then and I think they still are (for certain applications).
MS droids? Maybe.
Maybe MS tells them: No, you won't.
Maybe they just don't want to rewrite all their stuff. The number of actual core software developers was rather low, IIRC.
