We currently have duopoly which is not much better than actual monopoly.
The reason we don't have anti trust litigation is because neither GOP and DEMs are interested to do it and that's because these companies since them got smarter and heavily lobby.
When you write DEM in all caps just because GOP is written in all caps, you sound like one of the people who write MAC in all caps just because PC is all caps.
Not that the current administration is going to be performing any anti-trust litigation anyway.
