The privacy policy alone on whatsapp is what is keeping everyone I know off of it. It's egregious. FB is 100% snooping on what is being discussed, and if they are now moving to fully client-to-client encrypted on ALL chats (not just the ones you explicitly choose) it's only because they're losing market share to alternatives that are more trustworthy.
Remember when they tried to force everyone to accept the new terms or they would disable access after a certain date? Then they walked it back after people started using alternative platforms.
The privacy policy was never "walked back", they decided to do it anyway after the controversy (on HN and other platforms) died down.
Here's a newer article showing the metadata being sent to Facebook (presumably for advertising purposes), it includes your phone number, device ID, and location.
