Nice Summary of Darl McBride's Complete Loss of Reality
I find his idea particularly amusing that Novell and Redhat could have anything to do with whether Linux is free or not (aside from the fact that it was never free - even a download has costs). Does this joker seriously believe that projects like Debian would stop their work just because he talks nonsense?
Even if the GPL were attacked in some form (which hardly anyone besides SCO's leadership believes), that would only mean a portion of software would become problematic for Linux distributions. And a large part of GPL software comes from the FSF or has been transferred to the FSF - and is thus far outside SCO's reach. But they apparently never understood that a kernel isn't the whole system anyway, what can you expect from such trolls...
But what does SCO actually have to offer for the future? The partially over 10 years old Open Server? The Unixware that hasn't been developed significantly in 5 years? Ridiculous. The only somewhat modern product they have would be their Linux distribution.
