Copyright law says that if it is your work (unless you have a contract 
with eg your employer that says otherwise) you are the copyright OWNER.

As such, you are the person who GIVES the licence, who MAKES the 
conditions, and (within reason) you can do anything you like.

LibreOffice makes it a condition of ACCEPTING patches, that you give 
them the code under the terms of the MPL (or something compatible), any 
other upstream will make similar conditions - they won't ACCEPT it 
unless you give it to them on their terms.

The thing to remember is that if you wrote it - if it's your code - all 
the normal rules don't apply because you're on the *other* side of the 
contract. If you're writing much stuff you really need to have a solid 
grasp of the basics.
