Etymologically it means intelligence (and used literally, it meant "mind").
I can't find one, but have seen at least one instance with an umlaut over the second o, suggesting something more akin to "new-o-politik" to my mind, which would fit somewhat with long o ancient Greek stuff I remember from taking Greek in college long ago and far away.

The group behind that project support the idea that people who use software should have access to the source code of that software, and therefore requesting the "source" is an action they would encourage.
They are also responsible for individual pieces of software with names like "GNU Emacs":

Hopefully this information proves interesting and useful to someone, and I haven't merely made a silly joke less funny by explaining it.
This should leapfrog you in that specific direction: https://en.wikipedia.org/wiki/History_of_free_and_open-sourc...
That doesn't really clarify "the joke" for me. I don't see how that's a joke.
Classic Greek "long o" is literally a long o. The sound is drawn out at length.
So it seems likely to me this is pronounced similar to nootropics.
Like the term of yore, no-o-sphere (the sphere of the mind/intellect) https://en.wikipedia.org/wiki/Noosphere
