Not exactly an authoritative source. Take it from a Sun executive in charge of this, Tom Goguen:
Q: "Some vendors and end users have another concern – that Solaris will “fork” ... What can you say about the “forking” issue, and the potential for confusion"
A: "By making Sun’s commercial distribution of Solaris free, we think we’re going to mitigate the forking in terms of our primary market."
Hmmm, why would this Sun executive want to mitigate something that's not possible? Software under the MPL is forkable, and section 2.1(b) of the CDDL (the one you referenced) does not differ significantly from the same section in the MPL that it's based on.
Admit you're being hypocritical, or show me something better than what one Linux guy thinks of a license that was barely just released at the time.
Who said it was not possible? No one, proving how desperate you've become. I said you could face a patent suitfor forking, which remains absolutely correct. And of course why communists prefer GPL, and want to see our patent laws overturned.
