This article highlights all fundamental issues with #whatsapp business model but misses one particular issue, which actually made me remove WhatsApp from my primary phone: security exploits used for surveillance, as it was the case in 2019. The app is a closed-source binary blob that is analysed mostly by highly motivated and well-funded researchers, who sell exploits on zero-day market, leaving users exposed.

The story from 2019 that we should be talking about all the time:
"A security flaw in WhatsApp can be, and has been, exploited to inject spyware into victims' smartphones: all a snoop needs to do is make a booby-trapped voice call to a target's number, and they're in. The victim doesn't need to do a thing other than leave their phone on."
