I have only this to say to Mr. Peter Sunde: "fuck you. Thank you and good day." You can't have a messaging app as simple and ubiquitous as WhatsApp and have it be secure. Is it theoretically possible? Well... yeah, sorta kinda -- but only in the same way that it's theoretically possible for me to never pay my power bill again and have them forget and just leave the power on.TextSecure. Free. Open source. Uses the OTR protocol, I believe. The limitation? Android only. But it's as fucking simple as a stock messaging app. Take your pick: security or so-easy-anybody-can-do-it. I have yet to see or hear about a single program that got both right -- not a single fucking one. I doubt his will be the first, but hey... I've been wrong before.
