It really wouldnt. They'd keep using the OS and tools to sustain their systems until they got a replacement vendor supporting QNX or replaced the systems with non-QNX software. They might also sue original supplier.
So, rather grind to a halt, it would all continue running in legacy mode, users would spend more money, and it gets supported or replaced. Lots of precedents for that sort of thing.
Between acquisition price and QNX's revenues, it's unlikely support will be terminated any time soon. We wont get to see the hypothetical tested unless RIM bankrupts with nobody acquiring and supporting their assets. That a losing company acquired QNX did worry me a bit, though.
