RedHat is a company. Their products include:
RedHat Linux (now fairly obsolete)
RedHat Enterprise Linux (their comercial product, RHEL, which comes in a few different flavors)
Fedora
The whole quote (from RedHat's site) says:
The Fedora Project is a Red Hat sponsored and community-supported open source project. It is not a supported product of Red Hat, Inc. The goal? Work with the Linux community to build a complete, general purpose operating system exclusively from free software. Public forum. Open processes. A proving ground for new technology that may eventually make its way into Red Hat products.
I.E. we build it. If you want to add to it, and we like what you do, we'll use it... But it's ours. However, we're not putting up any support, because you're not paying for it. It's maily a test ground for stuff to go into RHEL.
It's exsactly like getting the free version of an old RedHat Linux... No support, but it is their work, and anything they like and get ahold of under the GPL.

NVidia drivers are closed, and while they beat the nv drivers in a few ways (TwinVeiw and hardware acceleration) there are features nv has that NVidia is missing. When in doubt buy an open card or card with open drivers... NVidia drivers have been a pain for me in that I can't get the NVidia drivers to compile with my current kernel, and if I upgrade/downgrade I lose my ivtv drivers. So, I keep patching, and waiting for a change in ivtv or NVidia so that I can get both on the same Debian system.
