The only fix to this is to replace phone numbers by secret 256 bit keys that are never reused...
Never gonna happen.
Never gonna happen.
1. They collect all the metadata in unencrypted format and link it to phone numbers, making a huge social graph.
2. Backups are not encrypted by default and enabling of them is pushed. So the messages were never actually encrypted for most people and police can get messages without the actual phone.
3. iCloud E2EE backup fight in UK was mostly because of 2. as people started to opt-in for encryption.
That doesn't make any sense. Why did uk want to start a fight over icloud E2EE backups (opt-in) but not whatsapp E2EE backups (opt-in)?
Default iCloud backup always included WhatsApp too, even if it was disabled in the app or the app used encrypted backups. And many other things, so it was not only about WhatsApp. Even for WhatsApp alone, it was slightly more useful.
Of 10,000 received messages, perhaps 2 are spam?
Nor were social security numbers.
But I suppose one could start a service, so you could pay them to look up a 3rd party's tax returns...
