There was nothing about screwing anyone involved in the choice of the license. The license had to be something all the copyright and license holders were prepared to accept (and getting them to accept CDDL was hard enough, not everyone did hence the few closed components).

Our belief was that Linux would be unlikely (and unwise as the overall system architecture is sufficiently different that it would be hard to port) to take the code. We expected - and encouraged - the concepts to be taken (as with the slab memory allocator).
