Two questions.
My family insist on using Whatsapp for the family chats. I have to keep a copy on a device just so I can communicate with them. I do so under protest, as I was always told it isn't secure. My brother has just said
"oh Whatsapp is encrypted, it's perfectly secure".
First, is it actually as encrypted and safe as my brother claims? That would solve everything.
Second, if it isn't, where can I get some proof that we should switch to Telegram or whatever? Proof which doesn't make me look like a raving loony?
Wider context matters
Two companies can advertise lockers with the same high quality lock, but one might still be better to use
Even if we specifically talk about security, one is better than the other.
WhatsApp has been endorsed by Moxie himself who invented Signal Protocol. What more do you want? Long winded talk for shit?

Appeals to authority are antithetical to any security assessment. Security is about capabilities, not about intentions.
