Oh, thank you, I should have paid more attention to the original article as well.
As a complete layman on the topic, I am kind of wary of (fully) homomorphic encryption. Not sure if I understand it right, but it seems to me that anybody in possession of the ciphertext would be able to run it through an arbitrary circuit, even if the result is encrypted and they cannot read it; in theory it would be vulnerable to MITM attacks.
For instance, say Facebook servers are compromised (yes, I know…) and an attacker then runs their own version of the recommendation algorithm instead, presenting fake ads to people that mention specific terms.
I am certainly several steps behind any academic discussions on the subject, so if that is not a problem I am curious to know why.
