I've re-posted this on Facebook on Sunday morning. I thought it was great content advocating free speech and the power of cryptography to support free speech. I could not believe that by Sunday afternoon I had received my first "community guideline strike for Spam" from Facebook. Suppose I was not really surprised, but now I know now first hand that Facebook censor anything they don't want their audience to see. Can't leave Facebook just yet but will as soon as I can.
