> I rather doubt Facebook is actually planning on implementing end-to-end encryption of the kind that would allow Facebook's product to hide their own data profiles from the Facebook advertising department, as that would defeat the whole purpose of the site. Targeted advertising based on Facebook's internal library of product data is the bread-and-butter of that outfit, isn't it? Well they might claim to add e2e encryption. But it won’t be true e2e. Will be fake like WhatsApp. They will still read the messages for advertising.
