> Current attempt to open source is a desperate move by QNX as their market share is disappearing

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).
