The EFF just published a damning analysis of WhatsApp's "Advanced Chat Privacy" that confirms what everyone suspected: it's complete bullshit designed to make you feel safe while Meta keeps collecting all the data that matters.
Based on the feature's documented functionality, it stops chat exports and auto-downloads but Meta still hoovers up metadata to build your behavioral profile. The EFF made it official: this is privacy theater, not real protection.
Meta Still Gets All Your Data
The EFF pointed out that "WhatsApp collects metadata, such as when a message is sent, who the messages are between, and where it is sent from." Advanced Chat Privacy doesn't touch any of that, so Meta keeps building detailed profiles of your behavior.
This metadata collection lets them track your relationships, communication habits, location, and social network without reading a single message. The "privacy" feature does absolutely nothing to stop this data harvesting.
The Feature is Broken by Design
Here's where it gets stupid: anyone in a conversation can toggle Advanced Chat Privacy on or off whenever they want. So if you turn it on for protection, the other person can just turn it off. Security researchers noted that this prioritizes convenience over actual security.
Plus it doesn't stop screenshots at all, which is how most people steal conversations anyway. The feature blocks automated exports but can't do shit about someone just taking a photo of their screen.
Nobody Knows What It Actually Does
The EFF warned that WhatsApp keeps adding complexity that makes it "harder to navigate the app, understand what each setting does, and properly protect conversation privacy." Most people have no idea what Advanced Chat Privacy actually protects, which creates false confidence.
Fact-checkers found viral misinformation claiming it stops Meta AI from reading conversations. It doesn't. This shows how badly Meta screwed up explaining what the feature actually does.
Why Signal Actually Works
The EFF pointed out that Signal does this right by minimizing metadata collection from the start. They use sealed sender so even Signal doesn't know who's messaging whom in most cases.
"Alternative encrypted chat options like Signal tend to thrive because they keep things simple and employ strong default settings and clear permissions," the EFF noted. WhatsApp's approach of adding more confusing features just makes privacy worse.
The AI Confusion Gets Worse
Advanced Chat Privacy supposedly disables some AI features in protected chats, but nobody knows which ones. Snopes found users are completely confused about what AI capabilities get blocked.
CyberPeace Foundation's fact-check showed that viral claims about blocking Meta AI were mostly bullshit. People think they're getting more protection than they actually are.
