Disappointed to see The Markup share advice for people to use WhatsApp in its post about preparing your phone for a protest, and that it's coming from "digital security trainers."

Metadata literally kills, and WhatsApp is swimming in it. The metadata they collect includes:

Groups you're a member of, location, personal info (email, phone number, user IDs), contacts and their phone numbers, in-app search history, when you use the app & how often you use it. E2EE alone doesn't guarantee #privacy

@alshafei any recommendations or links to breakdowns/discussions of telemetry gathered by the major messaging apps?
@cw If there is such a resource on telemetry specifically I'd love to see it too, the most extensive comparison I've come across thus far has been this: https://privacyspreadsheet.com/messaging-apps
