Five things companies can do to protect user privacy and free speech:
Respect your data.
Companies should carefully evaluate the costs of collecting and retaining data to avoid the fallout, lawsuits, and government fines that Path suffered for silently uploading users’ contacts.
Stand up for your users’ rights.
Companies can earn public praise and user trust for protecting user privacy rights like Amazon or for supporting free speech like Facebook.
Incorporate privacy and security from start to finish, and evaluate these practices as the company grows.
Give users the ability to make informed choices by letting them know what data you collect, and how it can be used, shared, or demanded by the government. Transparency reports like Google’s are important tools.
Encourage users to speak freely.
Give users control over the content they access and the tools they use rather than censoring content like PayPal.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
