I wish I could switch to Telegram, sadly most people I know use it as a "secondary" chat app for random/funny groups rather than their main app. What's even sadder is that I think most of us can agree that most people really don't care about privacy issues when it comes to apps, most "regular" people just want to use them for the sake of it. It's just people really focused on their privacy or "techies" the ones that have a concern about it.
