@MazonnaCara89 The country I live in (Brazil) overly uses and depends on WhatsApp. From government departments to businesses and transactional relations, all the way to social and family affairs, people is addicted to it, forcing other people (e.g. me) to either have a WhatsApp account or ending up far beyond mere social ostracism (beyond mere loneliness): effectively, the inability to buy, sell, rent or even resolve citizen matters with certain government/state departments (such as receiving medical appointment schedules from Brazilian's public health system (Sistema Unico de Saude/SUS (Unified Health System) via their "postinhos"/"Unidades Basicas de Saude" (neighborhood public health centers)). They don't even use the grand old phone calling and SMS anymore: even "calls", when performed, are made by people/departments/businesses via Whatsapp VoIP functionality.
That said, it's worth mentioning that WhatsApp has been running ads for a long time: the "Channels" section lists seemingly random "channels", many of which are businesses with "verified" "blue badges". So it's effectively advertisement disguised as veiled "recommendations" from Meta. It seems like it'll just become worse (to the surprise of no one who understands what Meta is).
I really want to leave WhatsApp, but I'm socially compelled to stay (it's the only mainstream platform where I still have an account, against my will)... the raw, grotesque distillation from social compliance, worse than depicted in Derren Brown's documentaries...
