You may be interested to read the following post that discusses the  
existing and alternative licenses with regards to OSM:

There is also a wiki page that links to the proposed license(s) and  
also contains a bit of criticism of even the proposed changed license:

I found this response to be helpful regarding the "GPL vs. BSD" debate  
in the context of OSM:

Other posters have shared most of the worst pitfalls with the current  
CC-SA license. The proposed license does clarify a great deal (though  
some concerns regarding commercial use remain) but it is still only  
*proposed* and there is no estimate as to when or how it will be  
enacted as far as I know.
