GPL is more restrictive than BSD. "Hijacking" is the bogeyman that Richard
Stallman tries to scare open source developers with: the notion that
someone could take open source code, modify and improve it without giving
back the changes, and use the resulting improved proprietary version to
eliminate the demand for the open source version. 

As far as I'm concerned, Stallman is just being paranoid. The only case I
know of that even remotely approximates this kind of hijacking is Windows
NT Name Service, which is a straight rip-off of Bind. Since NT does Bind
worse than Bind, I can't see that Bind has been hurt. Since NT has to
acknowledge where it got the code from, this helps spread the word about
Bind. The end result is that if anything, the proprietary clone is
helping, not hurting, the demand for the the open source version.

So I generally figure go BSD and be done with it. Keep life simple.
