@cnvi OP:
The US DOJ does nothing because we say nothing ... what do you expect?
What is stopping you from shouting/saying/speaking up/filing complaints/talking to attorneys/ demanding PUBCON has realistic discussions on this topic?
All but the last is US-centric and many of us are not American. That said, taken in order:
1.0 There is a cycle to both business and business regulation. The past several US administrations has been a time of corporate amalgamation. That the finance sector was almost totally bailed and let out of responsibility in 2008-2009 debacle is a prime example of the tail wagging the dog aka regulatory capture but it is far from the only. If ~9-million losing jobs, ~6-million losing houses, and ~$8-trillion value stock market loss (2008-9 in US alone) didn't get 'corrective action' why does anyone expect the same players to take on Google that is far more 'too big to fail' ridiculousness?
Note: FB is primarily in trouble for continually lying to authorities plus selling personal private data directly to third parties, i.e. Cambridge Analytics. Google parses commentary finely but rarely if ever actually lies plus sells 'black box' data use rather selling the data itself to third parties.
2.0 I and others speak up regularly and have for over a decade - however, rather than whinge I have recommended that folks (as I, myself, have done consistently) wean themselves from Google services/products as there is, generally, no actual legal recourse available against Google behaviours within the US itself. Those that disagree with that are quite free to take action.
Note: most/all web platforms are not actually monopolies in the traditional and legally recognised sense; rather they are corporate oligarchies and unless in collusion, such as with Adobe, Apple, Google, and Intel's wage fixing 'scandal', that will require both legal and political changes if they are to be constrained.
2.1 I and others, outside of the US, have made complaints/submissions, over the years to respective Privacy Commissioners, etc. and, on occasion, certain practices have been publicised and/or curtailed. Not that Google doesn't wield a great deal of power outside the US, it most definitely does, however the laws, regulations, expectations, traditions of other countries do sometimes catch Google by surprise, and Google doesn't always 'win' those encounters.
2.2 I never attend PubCon or similar conferences (they tend to be (1) not on the cutting edge of webdev (for about a decade) and (2) far too G-focussed). And those are likely reasons why the usual suspects aren't speaking up; they largely aren't either, their products/services being largely Google-centric.
Sooo...
Let's flog the dead horse once again...
In face of Google search monopoly, what can individuals do? 1. suffer until gone out of business.
2. find alternatives.
---Yes, they exist; yes, it is hard; yes, it takes time.
---Google owes you little to nothing, get over it; you are not in a partnership with Google: you are either their customer (advertiser) or their product (publisher); in neither case are you irreplaceable.
3. be fortunate; I know a few who are, and who still take primarily (90%+) Google traffic and Google revenue to the bank while it lasts; here's hoping you sell out or retire before the music stops.
