A conversation between me and my friend on Telegram:
Me: Hey, install Quicksy. I don't want to chat on Telegram, it's not E2EE.
Friend: No. I'm not going to install your weird apps.
Me: But, it's free software (স্বাধীন সফ্টওয়ার) and really good, supports E2EE!
Friend: No. I have nothing to fear. I don't care if someone reads my chats.
This went on for some minutes, I couldn't persuade him to install Quicksy. So I gave up.
After a week, when he was about to say something political on a Telegram voice call (this was E2EE)
Friend: I don't want to say it over phone, you know.
Me: Well, this call is E2EE, say whatever you want. Only you and me can hear it.
Then, he said it.
