How can you give consent to share with a third party what I have shared privately with you? Just because the TOS says so doesn’t make you exposing my private Information consentful.
Look at the example of what LinkedIn and WhatsApp and all its ilk does: I don’t want to be on those platforms. But friends upload their address books all the time, so I’m fairly sure they all have a full view of my social connections. How and where did I agree to that? How can my friends meaningfully consent to that on my behalf?
