[Interest] Contributor agreement rundown

[Nikos Chantziaras]

I went to register for a Gerrit account.  There I saw that I must agree 
to a "contributor agreement".  It's very legalese, so I'm not sure if it 
means what I think it means: Nokia can transform open source code I 
contribute into non-open code?

"Licensor hereby grants, in exchange for good and valuable 
consideration, the receipt and sufficiency of which is hereby 
acknowledged, to Nokia a sublicensable, irrevocable, perpetual, 
worldwide, non-exclusive, royalty-free and fully paid-up copyright and 
trade secret license to reproduce, adapt, translate, modify, and prepare 
derivative works of, publicly display, publicly perform, sublicense, 
make available and distribute Licensor Contribution(s) and any 
derivative works thereof under license terms of Nokia’s choosing 
including any Open Source Software license."

The beef is the phrase "under license terms of Nokia’s choosing", which 
can be an open license, but is not required to.

Did I understand that correctly?
