When he came to MIT's AI Lab, and gave a nice presentation on Plan 9, I asked him which of the ideas he had talked about we were allowed to use in our own software projects. He said "as far as I'm concerned, all of them". I asked if there were any patents that might matter as far as AT&T was concerned, and he said there were some, but that he didn't even understand the patent applications. I know that his talk made an impression: the innovation of the ideas, the impressiveness of the system built on them, and that not only didn't we know if we would be sued for using similar ideas in our own systems, but Rob wasn't going to tell us if that was possible or not. And then, years later, after Plan 9 failed to capture a big audience, it gets released for more public consumption, but for some incomprehensible reason, is still not free software. There are some pretty big reasons that Plan 9's very good ideas are sitting in an eddy of the stream of OS design: because the political shenanigans of those who hold the keys have done their best to keep those ideas out of the mainstream.
