Cryptography theatre: Snake oil cryptography as a legal technology. The real motive for the popularity of “E2E” amongst tech companies actually turns out to be fairly obvious: the purpose of adopting snake oil “E2E” is not to deliver actual security, but to act as a kind of cunning legal maneuver to exempt themselves from the usual legal obligation to honour warrants, subpoenas and other court orders. The core of the issue here is that the web is fundamentally designed around the premise of client-side code being distributed by the communications service it relates to; that these two things are coupled together.
