Originally published by Zack Rusin, found by using the WayBack Machine. I am not a lawyer and do not know legal stuff. I posted this here for my reference and in case the wayback machine loses the page. If this posting itself violates some kind of license let me know and I’ll take it down since I have no clue about licenses. The information here may or may not be out of date. Take it as a starting point to find out the differences between the licenses.
