The argument here is its unfair to bias ranking towards a preferred format. In this case, something about excluding competitors, except AMP is completely open-source[1] so...?
The counterargument is yes you can, because it's your pamphlet/newspaper/website and you're the editor, not the government.
Of course as a consumer, I don't really care whether it's some random company or Google who gets to violate my privacy, and I especially couldn't care less about lack of innovation in the privacy violation business, so I think the antitrust angle here is pretty slim.

No one is saying these broadcast groups don't have 1st amendment rights, just that they were going about it in an anti-competitive way.
The radio stations weren't broadcasting their prices to consumers, but secretly communicating with competitors to form a cartel, which is forbidden. Doesn't matter if they were radio stations or grocery stores.
