They're re-naming their free line to 'Fedora'.
And they're focusing their business on 'Enterprise-class' work. They obviously think they can compete with IBM, Sun and MS for a chunk of that market. It's a tactical choice, the same one made by IBM. It makes sense, for IBM, who makes most of their real money from hardware and software infrastructure.
I'm not sure I think it's a smart choice for Red Hat, but it is their choice.
And this once again underscores perhaps the biggest single reason to use Linux -- Linux will go on. If you're not happy with this, you can go with one of a dozen other distros.
If you were on a highly proprietary OS, like Solaris or Win2K3Server, and they made some move like this, you'd be screwed.
