OpenADP is Open source Advanced Data Protection for everyone. It defends vs secret mass surveillance via software transparency and distributed trust. That distributed trust is built through OpenADP servers run by volunteers around the world.
OpenADP has servers in the US, but for resistance to any one government, volunteers in several countries are needed. There is a quick-start guide for running OpenADP on a Raspberry PI. If you've got a Raspberry PI to spare, and some free time, consider volunteering for OpenADP.
