In the nineties, nets gate navigator put their really shitty internet explorer on windows. That's how they got in trouble with anti trust. The main thing it does now is block mergers that would lead to monopolies. So go back to the cell phone carriers, right? We had four of them only, classic alagopoly. While t mobile and sprint have tried a couple of times to merge,. Each time the justice department would block them or threaten to take them to court. Tand few in number. They won twice. And then the third time, sprint and t mobile last year decided, we're going to go to court. And they did win.
