I say leave it the way it is except define open source ecology on the wiki main and the blog page, and make the difference between FeF and OSE more readily apparent to people who might not be interested in reading further.  OSE is sort of a bizarre term with no apparent intuitively obvious meaning and I'm not sure if I could define it myself, much less explain why exactly the word ecology was chosen.  Sounds kind of like a randomly chosen buzzword actually although I gather it has something to do with technologies and interrelationships between them which makes sense but should be made more readily apparent.
