>Sun deliberately made the CDDL incompatible with the GPL! > >This is a claim supported primarily by one former employee of Sun. Others disagree. And even if it was verifiably true: What about Open Source values? Since when is the GPL the only acceptable Open Source license? Lots of hand-waving and false equivalency here. We're not talking about "Open Source values", we're talking specifically about the Linux kernel…
It is worth noting that the GPL2-CDDL license incompatibility is still a theoretical legal issue, and that there are differing learned opinions with respect to the confluence of the CDDL, GPL2, and ZFS. For instance, Eben Moglen, co-author of the GPL3, has indicated that incompatibility is not an issue[0]. Many Sun employees have also disagreed that Sun's intent was to make the CDDL incompatible with the GPL2.
