When I choose MIT over GPL I'm usually trying to make my work as easy for others to adopt as possible. I want some of the software I wrote to become a commodity. The MIT seems a clearer path to commoditized software than the GPL.
I think this is for one hyper-specific case that he in fact "okayed" the switch to BSD.
In response to the change of license, Richard Stallman of the Free
Software Foundation says, "I agree. It is wise to make some of the
Ogg Vorbis code available for use in proprietary software, so that
commercial companies doing proprietary software will use it, and help
Vorbis succeed in competition with other formats that would be
restricted against our use.
Is that a reasonable line of thinking?
