There was a lot of drama between BSD and AT&T even though the licenses were short too. There is also drama over MPEG formats due to patents, again, even despite the short licenses, which led to webm.

A short license does not mean that it will have fewer problems. It just means it addresses fewer concerns.

At any rate, the mjg is not complaining about software licenses, but about trademark policies. Trademarks are a very different set of laws than the copyrights that software licenses typically handle.
