FAANG are different a kind of monopoly - an unprecedented one for which no legislation exists. They have a monopoly on data, as brokers they control not only what companies may purchase for commercial services, but through curation of search results and news/social media feeds they control what information reaches the eyes of millions of people.

This is an unprecedented amount of power over society wielded by corporations and, in effect, the handful of private citizens who own them.

I tend to lean libertarian but I've questioned for a while if it's appropriate and/or possible to limit this power in an equitable manner...but unchecked Google alone can probably sway elections with algorithmic manipulation of search results and even selective autocompletion.

That's probably the entire reason that the administration is targeting these orgs, and while I don't agree with the administration I believe this particular endeavor may be for the greater good. When Twitter can delete videos retweeted by the president, or add "fact check warnings" which effectively (though maybe not truthfully) discredit his statements, Jack Dorsey and his board are wielding a more direct, more immediate, and possibly more effective power than any of other branches of government.
