Google is illegally monopolizing online advertising tech, judge rules

I've always been somewhat opposed to this, because there's already like 10 different search alternatives, and now AI is taking over, which will further weaken their grip.

Google is on top because they do the best job; I use Yandex primarily, but I switch back to google all the time for coding related questions. In terms of advertising, there's billions of views on Facebook/Instagram/X to get, in addition to all the other sites. I get they're a big player, but I worry we're just beating Google because they're down, not because it's good for the consumer.

This is not that case. This case is about how Google only serves certain ad inventory to people who use their products.

Then what is the definition of a monopoly? It doesn’t appear to be the same definition as “the exclusive possession or control of the supply of or trade in a commodity or service.” Do they exclusively control all ad inventory? Do they control all devices receiving ads? GP states that they don’t have exclusive control broadly, just within their own ecosystem. That’s not the definition of a monopoly though, so it seems like a motte and bailey calling google a monopoly.
