Everyday something new comes up with the security services of the world infringing our liberties. We write software, some of is it is open sourced, most of it has licenses.<p>How feasible would it be to add a clause to some of these licenses that denies the use of that software by security services for spying on their own people? Obviously some open source software would have a greater impact than others. What open source software is likely used by the NSA and GCHQ et al?<p>I'll start with OpenSSL!
You could use the HESSLA or similar. It would make the license non-opensource, and most of us consider such conditions to be a poor tradeoff (e.g. <a href="http://www.gnu.org/licenses/hessla.html" rel="nofollow">http://www.gnu.org/licenses/hessla.html</a> )
It's pretty clear that normal rules don't apply to the NSA or to GCHQ.<p>If you want to make a difference, it's probably best to call your congressman and let them know that you're deeply troubled by recent events.
