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.
I agree that mentioning them is not helpful if the question explicitly is about WhatsApp vs. Telegram. However, Signal surely is simple enough that it can be used by anyone capable of using WhatsApp. It free, encrypted and a lot more trustworthy than any F**book app ever will be.
