In many parts of the world Whatsapp is the dominate communication platform. My landlord sends me my utility bills through WhatsApp, as is my doctor’s scheduling platform, and my vet’s contact info, etc. It’s basically impossible to do things without it.

Probably because “Network effect”. Many places whatsapp is basically the texting app and you are fucking forced to use it

Seriously this. Fuck Meta and shame on OP. There are much less evil VoIP apps available.
