If I HAD to use one, which one would be better? While Whatsapp is owned by Facebook, they have end to end encryption for the messages, while the metadata is not. However, on Telegram, nothing is end to end encrypted unless you use a secret chat which most regular people are most likely not going to use. I have a feeling Whatsapp would be better but I wanted to hear your thoughts.
My choice is easy: Certainly not WhatsApp as their T&C state they pass metadata up to Facebook. Telegram I'm pretty happy with, as I like their silent send / scheduled send, and also massive groups (like my community has a group on it). I'm happy with their being banned more than once, that they're not actually selling user data.
But I also use Signal, Briar, Threema, Nostr, XMPP with OMEMO, etc depending on who I'm connected with.
