"Public Citizen is a national, nonprofit consumer advocacy organization founded in 1971 to represent consumer interests in Congress, the executive branch and the courts"
They do a lot of good work, but the stuff I know about personally includes representing people who couldn't afford lawyers in cases related to free speech online.
As a non-profit organization, we do not accept payment from clients and do not charge fees. In deciding whether to get involved in a case, our primary consideration is whether the case presents an opportunity to establish important precedents on behalf of consumers. If there are any court-awarded or common fund fees, or class action settlements including fees, we expect to receive a share commensurate with our involvement. On most occasions, we do ask that our out-of-pocket expenses be reimbursed.
There are probably a lot of people who could benefit from their help. Make sure you let people know they're out there. Click the picture to go to their website or click here for their contact page (useful if you want to request help from them).
