Not really. Linux won because the GPL has proven to be more suitable to businesses, and especially commercial open source business models as practiced by companies such as Cygnus and Red Hat.

BSD-style licenses tend to be a better fit for business models that sell proprietary extensions to free software. These form lock-in moats that inhibits the growth of any deeper ecosystems. We've seen this over and over again with things such as graphical subsystems for non-free UNIX, but also more recent examples with firewalls and storage boxes. Those are great for what they do, but work on the free parts are seen more like a gift to the community than a money maker.

The tit-for-tat model of the GPL enables those ecosystems to form. By forcing your competitors to free their code in exchange for yours, game theory dictates that moats cannot form, and when everyone stands on other's shoulders development is faster.

I'd say that's pretty much experimentally proven by now. Of course, reality is not as black and white, especially when GPL-style companies contribute to BSD-licensed software and vice versa. Perhaps PostgreSQL is a prominent example of that. There are however traces of these patterns there too, for example in how the many proprietary clustering solutions for the longest time kept the community from focusing on a standard way.
