Seeing how the dumb community feels trapped now that Meta stopped supporting KaiOS, I can tell there are a lot of people that wish they could leave the service. A lot of spaces make you feel like you have to use it, not want to use it. I used a few months while I was in the UK, but after that I’ve been lucky enough to delete my account as the service was useless elsewhere where other places I lived, no one used it.

…That said, I now have issues with LINE as a defacto chat option locally that gets in the way. My account was crushed after they canceled LINE Lite which was 10× smaller with no bloat or trackers & I refused to “upgrade” (where like WhatsApp & Signal, one is forced to have a mobile device as a primary device). Largely I can inconvenience everyone by making them choose a different means of communication (with email be largely the only common denominator) but if I were dating again, I would inevitably be forced to use the unsafe app putting myself in the position a lot of WhatsApp users feel they are without effective choice.

"some people use" ≠ “everybody wants to use”

(And are you sincerely suggesting WhatsApp, which is run by one of the largest and most aggressive privacy invaders the world has ever known, as a privacy friendly application? I would suggest re-thinking that position if you want to be taken seriously.)
