Since that was written, a nearly-all-free Windows-like system has been developed, but technically it is not at all like GNU or Unix, so it doesn't really affect this issue. Most of the kernel of Solaris has been made free, but if you wanted to make a free system out of that, aside from replacing the missing parts of the kernel, you would also need to put it into GNU or BSD.
