I don't get the complains here. Whatsapp is used by over a billion people and offers end2end encryption for them. A system that mainly targets people with little tech experience can never be kept 100% secure. If they make it harder to switch phones, people would stop using whatsapp. The only vulnerability seems to be that they could prevent delivery messages. I'm sure that most people would notice if they suddenly son't see the 2 ticks, even if the other person answered. And if you want your conversation to be secret, that's a major red flag, now that this is known. And if I get a phone change notification even though the other person didn't change their phones I'd also be confused at least. When I last changed my phone, a lot of people noticed because of the notification and asked me. And those were not tech savvy people, they were just wondering why I got a new phone. Spying on conversations (especially by govt agencies) is only effective if the target doesn't know about it. It seems that Whatsapp has no way of enforcing that without the user noticing.
