Do you have any sources for your claim about how the Clinton campaign acquired FB data and how they used it? Was any of it acquired fraudulently and/or in violation of FB's ToS, like CA's data was?
This is a thread about how CA acquired and used data from Facebook, so I assume the parent comment was trying to make an apples-to-apples comparison. The alternative is that the poster was disingenuously trying to imply a false equivalence.
Sigh....the technical legality of obtaining the data is not the point of contention. Do you think that is what this is about, whether CA "broke the law"?
