I'm actually leaning off of permissive licenses unless it is for something
important that needs to be standardized (like Opus) or like what 10gen does
by having the core copyleft yet the drivers permissive.
With projects like jQuery, they went from being dual licensed with the GPL
and then went just MIT. I think this was around the time they formed the
jQuery Foundation and potentially saw the GPL scare away potential commercial
contributors.
This is why I have been more interested lately in the MPL version 2. A
project like jQuery could keep the code copyleft (like the GPL) but then not
worry about issues with licensing if they wanted it linked or included with
FLOSS or commercial software.
