Google is illegally monopolizing online advertising tech, judge rules

Google isn't a monopoly in the Standard Oil sense of the term. Its ad revenue is big because it occupies so much user attention. I actually think many suggested remedies would actually make Google more profitable.

For example, prohibiting Apple-Style search deals would mean that Google gets a smaller amount of traffic, but that traffic would come with zero cost. That could end up being more profitable. A similar argument applies to Chrome or any other customer acquisition vehicle.

The real barriers to making Google competitive are fixable but require a different sort of regulation outside of antitrust.

I mean it wouldn't make sense for it to be more profitable for google if there were no search deals, since otherwise they would just cancel the deal themselves. Clearly they see long term value in blocking out competition even at that high of a price

It depends on the what the browsers end up doing. If they just surface a select your search engine dialog during set up, most people will just select google and nothing will have changed besides the cost. If they set a non-google search engine by default, they will lose ad revenue because of people not bothering to change the default.
