The recent NSA leak has me thinking. The some names of open source developers are attached to nasty stuff. Adding a clause similar to the form of: "If this software is misused by a state or government, legal retribution may be sought."<p>If in place, could this mitigate usage of good things being used in bad ways? Lawyers chime in.
State actors, when sufficiently motivated, are unlikely to be daunted by licensing terms. (Hell, private companies often violate license agreements in minor ways; meanwhile, state actors routinely violate international treaties / break into the networks of allies / perform illegal acts for unconvincing reasons.)
