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 people who use any #centralized, #SingleVendor and/or #SingleProvider #Communications Service like @signalapp , #WhatsApp, #Telegram, ... for anythibg serious should be disqualified per law to teach others about #InfoSec, #ComSec, #OpSec or #ITsec, because their #Disinformation will sooner or later kill people!
Use proper #E2EE and exercise #SelfCustody of #Keys, like with #XMPP+#OMEMO.
Fortunately, @monocles / #MonoclesChat, @gajim and others make that easy to do.
Fon't forget to NEVER EVER use #biometrics to unlock devices, properly encrypt your stuff and tunnel all comms over @torproject / #Tor so even if they eavedrop your entire comms, all they get is a garbled mess you can't decrypt even if you wanted to!
