This is from the Fedora web site:
The Fedora Project is a Red-Hat-sponsored and community-supported open source project. It is also a proving ground for new technology that may eventually make its way into Red Hat products.
It sounds to me like RH management is thinking "Why should we have a full-blown R & D department when we can exploit the "open source community" and use unpaid volunteer programmers to develop our products for free? We can then turn around and sell those products to our 'enterprise' customers for beaucoup bucks."
Just my opinion.
