The Justice Department and the states, which include New York and California, said Google had built its monopoly by buying up crucial tools that delivered ads to publishers. As a result, advertisers paid more for space on the internet and publishers made less money, as Google took its cut, they said.

I am not really buying into this very much. The DOJ has been weaponized and become a political tool of the left. Google is far left; it is probably just a reminder for them to start contributing more to the Democrats now or face the consequences.
On the other hand, Bill Gates has always been a lefty and the Clinton DOJ went after Microsoft. But at that time, it was fashionable in lefty circles to do anything that helped out Apple.
