The laws that rule software are moving fast because it is a new science. Because they do not have enough information, people that make the laws will possibly write them in such a way that Free Software cannot exist anymore. For instance the SIAE law in Italy imposes that every software being sold has to be registered. This registration costs money. This new law is a serious threat to the freedom of redistribution and therefore is a direct threat to the existence of Free Software.
Software patents are another kind of threat.
Each software is potentially attacked by a software patent. There is no way to find out if a software crosses a patent or not. Should software patents become legal in Europe, it would be potentially illegal to use, modify or redistribute all existing Free Software. We wish the situation to be less problematic. Since it's not the case, the FSF Europe has to fight to give a strong legal basis to Free Software.
