It is remarkable to think that only in the past 15-20 years have we moved most of our private communications to digital channels with centralized storage & the processing power to perform bulk scanning. Coincidentally that’s nearly as long as encrypted messaging has been around.
Many folks in law enforcement and politics seem genuinely confused about the popularity of end-to-end encrypted messaging, like we all just decided to become anarchists or something. That’s not at all the dynamic we’re seeing here. The entire basis of our communications infrastructure shifted in a direction that’s inimical to privacy; encryption is the obvious solution.
