Is Sun Turning against Linux and Red Hat?

An Elephant writes "Groklaw is reporting, based on a ZDNet UK story, that Sun's strategy for survival in the near future is based on trying to equate Linux with Red Hat, and then attack Red Hat as too small to support enterprises. This seems strange -- Sun is selling a Linux distro itself (the Java Desktop System). As I write this, there's no mention of this on Sun's website -- neither confirmation nor denial. What's going on?"
