To me, the OSS movement seems to be split between a minority of extreme idealism (Richard Stallman's position on the importance of software Freedom), and a majority of mostly big corporate pragmatists, which have realized that is far more lucrative to share the burden of developing common infrastructure between themselves than the previous status quo; and who greatly dislike anyone who tries to co-opt the OSS movement into something which does not serve this purpose. There is also a 3rd camp of companies that want to sell proprietary software, but who have noticed that open source variants of their software are a better marketing strategy than the shareware and freeware of old.
I believe that this third group is the biggest annoyance to both of the traditional OSS communities, but also the only ones who can actually make money by selling software whe also showing users exactly what code they are actually running.
