in 2018, Facebook told Vox that it doesn’t use private messages for ad targeting. But a few months later, The New York Times, citing “hundreds of pages of Facebook documents,” reported that Facebook “gave Netflix and Spotify the ability to read Facebook users’ private messages.”
Surprising? No. Appalling? Yes.
If you backed up your phone with Google or iCloud pre backup encryption, which is most people, then yes!
WhatsApp backup of Google drive is not encrypted?
I don’t think so
it is now iirc
it used to not be for a long time, even after they’ve introduced e2ee for messages.
No, WhatsApp backups are e2ee even on GDrive, although I disabled any cloud backups ages ago, and prefer manual database copy/paste syncing.
