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?
It's a rage-bait, avoid trolls like them. Whatsapp is close-sourced - so we don't know shit about how good their encryption is - remember how phone numbers were showing up on Google Search? Yeah. Meta also works with the local government to suppress "fake news" - so, how exactly does it know what the contents are, without breaking encryption? These are two of the most convincing reason to not use the app.
You've been nothing but rude in this entire conversation. You havent articulated a rationale in any of your messages for your position that encryption doesn't matter, or that closed source is good enough. You don't have a clear and defensible argument that we can engage with. You're just throwing insults, granted most of the insults are passive insults, so kudos for that.
Using the Voyager app I never see anybody's profile photos I don't even think I have one.
For what it's worth I don't think this guy's a troll. I think he doesn't have the social graces to have a productive discussion. So he drives by a conversation drops his opinion you either agree with it or your insulted. There's no growth, but I think it's a very genuine human behind that keyboard emoting genuinely.
