A brief history of the surveillance debate:
2012: "Mass surveillance is fine — if it wasn’t, you’d see major corporations trying to court new business by building in crypto tools that kept out the surveillance agencies. The fact that they’re not doing this tells you that surveillance opponents are an out-of-touch, paranoid minority."
2016: "Mass surveillance is necessary — when companies use crypto tools as ‘marketing ploys,’ they’re getting in the way of something we all agree is proportionate and legitimate!"
