Iranian state television has urged people to remove WhatsApp from their smart phones, alleging without specific evidence that the messaging app gathered user information to send to Israel.
They are basically at war with the US and there is this piece of US Tech that nearly everyone is carrying around and that can access their communications, precise location, microphone and camera.
It's also owned by a company, Meta, that has a history of being used as a tool to manipulate public opinion.
I have no particular sympathy for Iran's leadership but I can understand why they would advice that (and I don't think WhatsApp is the only way for people to communicate with the outside world).
The only people making Iranians suffer at the moment are the Zionist fascists and their US proxies. They've already killed 1200 people in their unprovoked attack, including with terrorism and car bombs.
Don't forget Trump telling the ENTIRE city of Tehran with a population the size of New York to "evacuate"
Big US Corp is in bed with money and power. Right now, that means MAGA and that does mean fascism & Zionists. The tech itself can be ok. Though WhatsApp/Facebook isn't.
