No, but it is useless to worry about them getting an OS.
Ridiculous, as is the notion they could build something equal on their own.
You seem to have this strange idea that all of China is a backwards country, when in fact they've been graduating CS majors and engineers by the hundreds of thousands and sending students out all over the world. Also remember that high-tech Hong Kong belongs to them now.
You even allow them to rename and resell the products under a different name, as if there's absolutely nothing wrong with that
They could do the same with Solaris under Sun's CDDL, nothing in the license prevents it. In fact, the CDDL is even better for them since they could keep more of their code proprietary, just releasing the source for the CDDL portion of their product. Oh, nevermind, you like Solaris being open source so that's okay.
Open Solaris is not the same as Solaris, and if anyone attempted forking of Open Solaris they could be sued by Sun for patent infringement, making forking of it very unlikely.
