Apparently Red Hat’s FUD campaign extends to more than just mono. From a computing.co.uk interview with Matthew Szulik:

Why Red Hat versus Novell-SuSE or Sun JDS on the desktop?

They’re all proprietary except us. They all have proprietary technology inside, not 100 per cent open source software. They continue to lock customers in to limit choice.

If you buy the Sun desktop, you’re going to buy into the proprietary Sun architecture. With SuSE there’s Red Carpet, integrated with other Novell technologies, still proprietary.

I’m sorry, did I miss something? Was RHN recently freed unto the world? Sigh.
