The new privacy policy just reformatted how data is shared with facebook from the "Affiliated Companies" section to a new section "How We Work With Other Facebook Companies", but the only real change is, like the bullet point says, an added sentence about how data might be shared to integrate whatsapp into other facebook products, and it's clearly "integrate" in the functional sense.
Similar to facebook messenger recently adding instagram messaging, they're probably planning to add whastapp messenging too. I imagine this change isn't in the EU privacy policy just because just like the integram change, more product integration there is held up by antitrust action.
Notably, facebook using whatsapp data for ad targeting has been allowed by the privacy policy since 2016
I say “manipulative and evil”.
It's mostly "sorry that you don't understand how things work". I've seen this before with these privacy-invading megacorps. They're tone deaf and defensive. Maybe they're worried that people are catching on and the tides are shifting.
