In 2019, Edward Snowden said this about WhatsApp:
“The problem with applications like WhatsApp is, it was actually designed to have very strong encryption, just the same as the gold standard today which would be the signal messenger or the wire messenger, but then it was bought by Facebook because it was so good, and now Facebook is quite aggressively reducing the security of WhatsApp about once a quarter, and they’re trying to do it as quietly as possible, so a messenger that the people are comfortable using now is actually a danger to you.”
When Snowden speaks, you listen!
WhatsApp’s “E2E encryption by default” claim is a giant consumer fraud: ~95% of private messages on WhatsApp end up in plain-text backups on Apple/Google servers — not E2E-encrypted. Backup encryption is optional, and few people enable it — let alone use strong passwords.
