Common in Italy too. I find it very useful because you can send doctors exams, images, and so forth without interrupting like with a call. But is a lot more real time and personal than emails.
Don't you have any issues with sending your detailed medical information to Facebook?
Signal, or even Telegram (despite it's stupid crypto, the E2E stuff _should_ work if verified right, and it's a marginally better client at the moment) should suffice without sacrificing privacy.
I totally understand the privacy implications, but I'm a person that tends to extern all its personal facts, so I'm kinda "public" by default, so no worry about sending what I talk about with even with strangers.
Privacy is obviously good but when I ask myself what specifically bad has happened to me because Facebook and Google know a bunch of random information about me I'm at a loss. Until the problem of privacy is tangible to most people it will always be an uphill battle
