@antoinechambertloir When I definitely switched, 1 year ago, I had approx. 20 close people I wanted to keep contact with. I explained 20 times my personal concerns for not using Whatsapp, said I will remove it at some date (1 month ahead) and that I was and will be reachable on a very similar-looking application, called Signal, that matched my minimal privacy requirements. I invited them to try. Result: except my brother and mother, who now send me bare SMS, everyone did the move!
