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?
It creates a cost for spammers. They have to have an account with a Telco, which isn’t free, which in a lot of countries comes with some sort of National ID to register. That’s the reason.
No they don’t, you can sign up with a VoIP provider.
