You are making a bunch of assertions with no basis. WhatsApp's encryption hasn't been weakened. FB can't look at encrypted message content, neither can WhatsApp. A lot of people use WhatsApp because of the encryption guarantees, please don't spread unverified claims.

Facebook owns the communication end points and can do whatever they want with the message contents before they're sent encrypted.

Given their history, I would be surprised if they don't do some on-device metadata analysis.

>WhatsApp's end to end encryption and mining your conversations so under the hood the experience is radically different.

An anecdotal experience i might just chaulk up to coincidence if not for this but, was talking with a friend in WhatsApp something about babies, my friend was browsing Facebook at the same time about a minute or two after our conversation about babies, my friend started getting a bunch of baby videos popping in her Facebook feed that hadn't been there prior to our conversation.

Oh I know! I just mean that the product _feels_ nearly identical (apart from stickers which aren't intrusive) to how it felt pre-acquisition.

is there any evidence of WhatsApp conversations being monitored?

Last I checked:

Actual text of convo: not yet but soon. Metadata: yes.

So you believe whatsapp is not e2e encrypted? Or they're going to roll it back?

They don’t need to roll-back the E2E encryption, they can just access the data right there on the device after it’s decrypted and upload data back to FB via a sidecar. It will start with basic mining of content on the device with ‘anonymous’ summary or aggregate data being uploaded but it’s a slippery slope...

would you trust Facebook after the many ways they've sold your data?

Facebook doesn't sell data
