> One module is the operating system kernel, which is based on a proprietary real-time operating system (RTOS) kernel called “ThreadX”. The developer, Express Logic, sells licenses and source code for ThreadX. Customers such as Intel are forbidden from disclosing or sublicensing the ThreadX source code.

Now that Microsoft has acquired Express Project [0], I wonder if those terms will change, especially since they're trying to compete in IoT against Amazon (who acquired FreeRTOS). Of course, this is a relatively small issue compared to the rest highlighted in the post though.
