I currently use Telegram for my friends and family, but have reluctantly come to the conclusion that the UK Government is either reaching agreement for backdoors with messaging services, or is trying its hardest to.
I’m also on Element/Matrix. Before I try to get my contacts to join me on there, should I be aware of any privacy issues or is that a good place to head?
I used to do something like this before Signal became a thing. We used to use OTR via the Pidgin OTR plugin to send encrypted messages over Google Hangouts. Funnily enough, I’m pretty sure Pidgin supports Discord, so you could use the exact same setup to achieve what you described.
It was pretty funny to check the official Hangouts web client and see nonsensical text being sent.
