If you live outside the US, it's even worse with WhatsApp.
If for whatever reason you dislike WhatsApp, you just can't also be a society's functioning member.
Some companies have decided to deprecate email and phone support and only have a WhatsApp chat, potentially with AI slop. I've had to discontinue my services with some of these companies because of that.
Even some government services are going through WhatsApp; I've had to be there in person, among senior citizens just because of their tech choices.
I pretty much vouch for "vote with your wallet," but I am running out of alternatives.
