It's a nice bit of semantic ju-jitsu to say "they take this data and sell a service that wouldn't be possible without it" isn't the same as "selling this data," isn't it? Especially given that the targeting mechanisms don't have any k-anonymity guarantees, and I'm aware of at least one paper showing information leaks through the ad portal [1] https://www.ftc.gov/system/files/documents/public_events/122...
Seems to me like you're more playing "semantic ju-jitsu" than OP. Facebook collect data to sell targetted adspace, they do not sell data. This is a plain fact.
From a user privacy perspective, I’m skeeved out that Facebook sells access to data rather than giving out copies. The only difference is that Facebook makes more money.
It’s like those asshole companies that say they don’t sell data, but only rent it. That’s not the point that I care about.
