That is, when you acquire a product (for free, or for a fee) -- it seeks to make sure that you can do use that product as you wish. And that if you re-sell it, or share it, those same rights are available for the next user down the line.

So, it is all about freedoms, just maybe not the freedoms that some developers thinks it is/should be about.
