Typical users aren't programmers. For them there isn't a difference. GPL or BSD usually mean for the user to get Software for free. Where free licences really matter is for developers. The question is wether they have to give back their work that is based on other software. A really important point in this discussion is the question if something is still the same thing when you change it. In my opinion this isn't true for software. The orignal will still be preserved and still be free.
