>What does privacy rules have to do with monopoly or anti-trust?

They are becoming related.

Monopoly laws traditionally apply to commercial transactions. Facebook's customers are not experiencing a monopoly, they can easily switch to other ad-space vendors.

Many of Facebook's "crop" however happen to be voters who feel new laws are required to deal with Facebook's "network monopoly" especially as it is entirely arbitrary, harmful and very profitable.

Privacy aka legal ownership and control of data is one way to erode that "network monopoly".
