Reminds me of the senator that asked Zuckerberg how do they make money [0], and Zuckerberg simply said they run ads. What a way to use your questioning time, with something that was a google search away.
It seems more likely to me that the Senator was out of his depth.
But "ads" is pretty euphemistic -- to the point of dishonesty -- when the ads are targeted political campaign messages, for example.
Cambridge Analytica was at least enabled by Facebook.
I'd say that their operations could be summed up more reasonably by "Facebook track people".
