In business - "the hard part" == "competitive advantage" . If you open source that , soon you'll see more competitors knocking on your doors. For example, if intel wanted, it could have built a decent FPGA, probably in a reasonable time(there were startups that built decent fpga's). But building good fpga software ? that it couldn't do, first because it's really hard and second because you need tens of thousands of designs from your customers to run on this in ordered to make good software. That's not something acquirable.
