I need convincing. Facebook can't monetize end-to-end encryption, and WhatsApp doesn't ask before uploading my contacts. Encryption from the client to the server is a start, but there's not enough here to make me use it.
Completely right. Facebook paid $19Bn for whatsapp. How is not being able to keyword-search messages going to help them cover some of that cost? It sounds great but doesn't add up.
